Q

The 701D engine on the UH-60M has the DECs or EDECUs that replace the ECUs found in the UH-60A. The DECs or EDECUs improve transient droop compensation how? Explain how and when the DEC limits TGT.

A

Compensates droop during some maneuvers by monitoring engine torque, collective rate of change, and NR rate of change.

The temperature limiting system limits fuel flow when the TGT reaches the dual engine 10 minute limiting value of approximately 879°C. The automatic contingency power limiting will switch to a higher single-engine 2½ minute temperature limiting value of approximately 903°C when the opposite Q is less than 50%.

*** The DEC commands the HMU to limit fuel when TGT reaches its limiting value.

Dual engine TGT 879 +/- 9
Contingency TGT 903 +/- 10

Q

Explain when the EDECU limits TGT.

A

When the EDECU senses excessive rotor/NP droop. On engines with the EDECU installed, the TGT will bypass the 10 minute limiter and limit at the 2.5 minute contingency power setting when any of the following conditions are met: NP drops below 96%; greater than 3% droop between reference NP and actual NP; greater than 5% per second NP droop rate exists and NP less than or equal to NP reference speed. Unlike the DEC, the EDECU is not dependent on the other engine’s Q being less than 50%.

*** Dual engine TGT 879 +/- 9
Contingency TGT 903 +/- 10

Q

What are DEC/EDECU fault codes? How are DEC/EDECU fault codes displayed?

A

If a failure occurred on a selected input signal, the failed component or related circuit will be identified by a pre-selected fault code displayed as a Q value. These are also displayed on the FMS DEC status page. They are displayed for 4seconds on, 2 seconds off, starting with the lowest code and rotating through all applicable codes, then repeating the cycle. They will only be displayed 30 seconds after both engines are shutdown with AC power applied.

Q

How is the EMER SE-IAS (Item 15) derived from the PPC? When do I have to use this EMER SE-IAS and must I have one or two EMER SE-IAS’s?

A

Selected from the MIN/MAX-IAS (single engine) range computed in item 29. It is used immediately following an EP that requires Establishing S-E A/S. Normally only one is selected but two may be selected when item 29 is a wide range. 1-Slow and 1-Fast based on mission profile.

*** Note. The EMER SE-IAS is the emergency single-engine indicated airspeed (IAS) based on the mission and briefed to the crew for the purpose of crew coordination. This airspeed is selected from the MIN/MAX-IAS (SINGLE ENGINE) range computed in item 29, CRUISE data, and is used immediately following an emergency that requires adjustment to single-engine airspeed. When an aircraft does not have single-engine capability, the MAX ENDURANCE-IAS (DUAL ENGINE), item 24, or the OPTIMUM IAS AT MAX ALLOWABLE GWT (SINGLE ENGINE), item 34, as appropriate should be briefed as the emergency single-engine airspeed.

Note. Normally only one EMER SE-IAS is selected. However, when the MIN/MAX-IAS (SINGLE ENGINE) range, item 29, is wide, the crew may select two emergency single-engine airspeeds, one slow and one fast based on mission profile, modes of flight, environmental conditions or other factors.

Q

Define Effective Translational Lift.

A

ETL occurs between 16-24 Knots, when the rotor completely outruns the recirculation of old vortexes and begins to work in relatively undisturbed air. The increased efficiency continues with A/S increase until reaching Best Rate of Climb A/S and total drag is at it’s lowest point.

***occurs with the helicopter at about 16 to 24 knots, when the rotor—depending on size, blade area, and RPM of the rotor system—completely outruns the recirculation of old vortexes and begins to work in relatively undisturbed air. The rotor no longer pumps the air in a circular pattern but continually flies into undisturbed air. The flow of air through the rotor system is more horizontal, therefore induced flow and induced drag are reduced. The AOA is subsequently increased, which makes the rotor system operate more efficiently. This increased efficiency continues with increased airspeed until the best climb airspeed is reached, when total drag is at its’ lowest point. Greater airspeeds result in lower efficiency due to increased parasite drag.

Q

While in cruise flight at 100 KIAS and 46% torque, you notice ice starting to form on the aircraft. As the ice builds more torque is required to maintain level flight. What actions are required if the torque required to maintain level flight increases to 66% or more? What does this indicate may no longer be possible?

A

If icing conditions are encountered, turn on all anti-icing equipment immediately. If torque required increases 20% above that required for level flight at the airspeed being maintained before entering icing, exit the icing environment or land as soon as possible. A 20% torque increase indicates that normal auto rotational NR may not be possible, should dual-engine failure occur.

Q

What is the NOTE in UH-60 ATM Module 8 regarding the digitization of the cockpit?

A

(NOTE)

Digitization of the crew compartments has expanded and redefined the lines of responsibility for each crewmember. The enhanced ability for either PI to perform most aircraft/system functions from their crew station breaks down the standard delineation of duties and has added capabilities and potential distractions, in training and in combat. This could mean that during an unforeseen event, one PI may attempt to resolve the situation rather than seeking assistance from or even communicating that action with the other crewmember. It is essential for the PC to brief specific duties prior to stepping into the aircraft. Effective sharing of tasks relies on good crew coordination and information management.

While starting the aircraft for a DAY VFR flight it is discovered that the #4 MFD will only display the PFD and Engine Instrument Caution Advisory System (EICAS) pages and the #2 MFD is inoperative. Is it still legal to fly the aircraft?

A

Yes according to AWR 1726 R26

***A Multifunction Display (MFD) is considered operational if the Primary Flight Display (PFD) and Engine Instrument Caution Advisory System (EICAS) pages can be displayed and provide the required information. The ability to select the desired bezel functions on the MFD with the Multi-Function Slew controller (MFSU) or Collective Slew Control is an acceptable method to control the desired function when individual buttons on the MFD are bruised or inoperative.

MFD’s in position 1, 3, and 4 must be operational. An inoperative outboard MFD will result in loss of the barometric altimeter information on the inboard MFD. The #3 MFD is the only MFD position powered by DC Essential power and must be operational should an electrical failure occur.

Explain Collective/Airspeed to Yaw (Electronic Coupling).

A

Compensates for the torque effect caused by changes in collective position. It decreases tail rotor pitch as airspeed increases and the tail rotor and cambered fin become more efficient.

a) The #2 Flight Control Computer commands the yaw trim actuator to change tail rotor pitch as collective position changes.
b) The amount of tail rotor pitch change is proportional to airspeed. Maximum mixing occurs from 0 to 40 knots. The amount of mixing decreases until 100 knots, after which no mixing occurs.

Q

Define Dynamic Rollover and the conditions required for it to occur?

A

A helicopter is susceptible to a lateral-rolling tendency called dynamic rollover. Dynamic rollover can occur on level ground as well as during a slope or crosswind landing and takeoff. Three conditions are required for dynamic rollover— pivot point, rolling motion, and exceed critical angle.

Q

What is the Note associated with Slope Landing Limitations?

A

Because of the flat profile of the main transmission and forward location of both transmission oil pumps, transmission oil pressure will drop during nose-up slope operations. At slope angle of 10°, an indicated oil pressure of 30 to 35 psi is normal; and at a 15° slope angle, a pressure in the range of 10 to 15 psi is normal due to pitching of the helicopter.

Q

Discuss the heading hold functions in FPS above and below 50 knots.

A

The yaw axis of the FPS provides heading hold at airspeeds less than 50 knots and heading hold or turn coordination at airspeeds greater than 50 knots. For heading hold operation at airspeeds less than 50 knots, the helicopter is maneuvered to the desired heading with feet on pedals. When trimmed at the desired heading, the pilot may remove feet from pedals, at which time the existing heading becomes the reference, which is automatically held. To change heading, the pilot may activate one or both pedal switches, trim to the desired heading and remove feet from pedals. Alternatively, below 50 KIAS the four-way collective trim beeper may be used to slew the aircraft to the desired heading.

At airspeeds greater than 50 knots, heading hold will be automatically disengaged and coordinated turn engaged under these conditions:

(a) TRIM switches actuated in the lateral direction.
(b) TRIM REL switch is pressed and roll attitude is greater the 2.5°.
(c) Approximately ½ inch cyclic displacement and a roll attitude of approximately 1.0°.
(d) Heading hold is automatically reengaged and turn coordination is disengaged upon recovery from the turn when the lateral stick force, roll attitude, and yaw rate are within prescribed limits.
(e) Alternatively, when HDG is not engaged with a coupled FD, the collective trim beeper may be used to establish a standard rate turn.
(4) To make a coordinated turn, the pilot enters a turn under one of these conditions:
(a) Changing reference roll attitude by pressing the TRIM switch in the desired lateral direction.
(b) Pressing the TRIM REL switch and establishing the desired bank angle with feet off the pedal switches.
(c) Exerting a lateral force on the cyclic to achieve the desired bank angle, and then neutralizing the force with the TRIM switch.
(d) Keeping a lateral force on the cyclic for the duration of the turn.

Q

What is the recommended airspeed for Autorotation in a UH-60? Below what airspeed during an autorotation will the rate of descent increase while the glide distance decreases? What should be considered when discussing pitch attitudes of the helicopter during deceleration?

A

The recommended airspeed for autorotation is 80 KIAS. Autorotation below 80 knots is not recommended because the deceleration does not effectively arrest the rate of descent. Adjusting the cyclic and collective control to maintain 100% NR and 110 KIAS (100 KIAS high drag) will result in achieving the maximum glide distance. A landing area must be selected immediately after both engines fail. As airspeed decreases below 64 KIAS, the rate of descent will increase and glide distance will decrease.

Pitch attitudes up to 25° at the point of touchdown normally result in an adequate deceleration and safe landing. Withpitch attitude beyond 25° there is the possibility of ground contact with the stabilator trailing edge.

Q

Explain why the aircraft hangs slightly left wheel low at a hover. What component on the aircraft corrects this aerodynamic phenomena?

A

When the rotor disk is tilted left to counteract the translating tendency, the fuselage follows the main rotor mast and hangs slightly low on the left side.

Due to the MMU compensating for translating tendency.

*** Collective to Roll - Compensates for the rolling moments and translating tendency caused by changes in tail rotor thrust. The mixing unit provides left lateral input to the main rotor system as collective is increased and right lateral input as collective is de-creased.

Q

During shutdown, the droops fail to return to the static position during rotor coast down. What are your actions? Additionally, how low will the blade/blades droop in feet from the ground?

A

If one or more droop stops do not go in during rotor shutdown, shut down an engine to lower rotor idling NR in an attempt to seat the droop stops. If droop stops still do not go in, accelerate rotor to above 75% NR. Repeat rotor shut-down procedures slightly displacing cyclic in an attempt to dislodge jammed droop stop. If droop stops still do not go in, make certain that rotor disc area is clear of personnel and proceed with normal shutdown procedures while keeping cyclic in neutral position.

When the droop stops do not return to the static position, the main rotor blades may droop to within 4 feet of the ground during shutdown.

A

Basic weight of an aircraft is weight including all hydraulic and oil systems full, trapped and unusable fuel, and all fixed equipment. From basic weight total, it is only necessary to add crew, fuel, cargo, and ammunition (if carried) when determining the aircraft’s gross weight. Basic weight varies with structural modifications and changes of fixed aircraft equipment.

Operating weight includes basic weight plus aircrew, aircrew’s baggage, emergency gear, and other equipment required. Operating weight does not include weight of fuel, ammunition, bombs, cargo, or external auxiliary fuel tanks if such tanks are to be disposed of during flight.

Define total aerodynamic force (TAF).

A

TAF is the result or lift and drag and acts at the center of pressure

As air flows around an airfoil, a pressure differential develops between the upper and lower surfaces. The differential, combined with air resistance to passage of the airfoil, creates a force on the airfoil. This is known as TAF (figure 1-39). TAF acts at the center of pressure on the airfoil and is normally inclined up and rear. TAF, sometimes called resultant force, may be divided into two components, lift and drag.

What are the CAUTION’S associated with ground taxi and how do we perform ground taxi?

A

(CAUTION)
When performing these maneuvers, cyclic inputs should be minimized to prevent droop stop pounding.

(CAUTION)
Landing and searchlight have less than one foot ground clearance when extended. Use caution when taxiing over rough terrain when landing light and/or searchlight are extended.

(How to)
Increase collective and place cyclic forward of neutral to start forward movement. Minimize forward cyclic movement to prevent droop stop pounding. Reduce collective to minimum required to maintain forward movement. Soft or rough terrain may require additional collective pitch. The use of excessive collective pitch during taxi, especially at light gross weights, can cause the tail wheel to bounce. Regulate taxi speed with cyclic and collective and control heading with pedals. Use brakes as required.

The outer-loop (Trim) provides long-term inputs by trimming the flight controls to the position required to maintain the selected flight attitude. It is capable of driving the flight controls throughout their full range of travel (100% authority) at a limited rate of 10% per second.

Both inner and outer loops allow for complete pilot override through the normal use of the flight controls.

List and define the three no-lift areas on the rotor system.

A

Reverse flow - At the root of the retreating blade is an area where the air flows backward from the trailing to the leading edge of the blade. This is due to wind created by forward airspeed being greater than rotational velocity at this point on the blade.

Negative stall - In the negative stall area, rotational velocity exceeds forward flight velocity, causing resultant relative wind to move toward the leading edge. The resultant relative wind is so far above the chord line, a negative AOA above the critical AOA results. The blade stalls with a negative AOA.

Negative lift - In the negative lift area, rotational velocity, induced flow, and blade flapping combine to reduce the AOA from a negative stall to an AOA that causes the blade to produce negative lift.

Reverse Flow- air flows backward from the trailing to the leading edge of the blade. This is due to wind created by forward airspeed being greater than rotational velocity.

Negative Stall- rotational velocity exceeds forward flight velocity, causing resultant relative wind to move toward the leading edge. The resultant relative wind is so far above the chord line, a negative AOA above the critical AOA results.

Q

What is the difference between EARLY and OVER options on the flight plan screen?

A

When OVER (overfly) is active, the aircraft will overfly the waypoint and will fly a teardrop pattern to intercept the outbound leg. When the capture criteria is EARLY and the turn is less than 120°, the helicopter will roll out exactly on the next leg of the flight plan. When the turn is greater than 120° the helicopter will fly a teardrop pattern to intercept the outbound leg. If there is no next leg, OVER capture criteria will be used.

FMS uses actual track rather than desired track in calculating turn anticipation, to allow for low-level tactical flight where the final track to away point may not be along the desired track.

Q

How does the TFMP define Air Control Point, where are they designated and what may allow them to be placed farther apart?

A

An easily identifiable point on the terrain or an electronic NAVAID used to provide necessary control during air movement. ACPs are generally designated at each point where the flight route or air corridor makes a definite change in any direction and at any other point deemed necessary for timing or control of the operation. ACPs should be progressively closer as an aircraft nears the objective, facilitating timing and navigation. Type of terrain, illumination, total route distance, and accuracy of onboard navigation systems may allow selection of ACPs much further apart.

Q

What are the two basic maps used in tactical flight mission planning, and what are the advantages/disadvantages of each?

A

the JOG and the tactical map

The Joint Operations Graphic has a scale of 1:250,000. The scale of the map permits a relatively small map uncluttered with extraneous information. It shows coordinates in Latitude and Longitude, as well as Military Grid Reference System (MGRS). It is useful for performing long enroute legs performed at Low Level. However, because it lacks adequate terrain detail, it should not be used for Contour or Nap of the Earth (NOE) planning and navigation.

The tactical map has a scale of 1:50,000 and is a highly detailed map. This is the primary map used for the objective phase of the operation. It should be used anytime Contour or NOE flight is conducted, or anytime precise navigation is required (i.e. at a PZ or LZ).

What does the TFMP state you should consider when planning and plotting routes regarding:

Location of SP &amp; RP 
Selection of ACP's 
Turns enroute 
Route Width 
Course to be flown from RP to LZ
A

Route Planning - - The route for the mission must be tactically sound, yet not so difficult as to preclude successful navigation. The first step is to determine the threat situation. The following are considerations for planning and plotting the route:

a. The easiest, quickest and least hazardous mode of flight is Low Level. It should be used whenever the threat situation allows.
b. Contour and NOE are progressively slower, more difficult and more hazardous, and should only be used when the threat situation dictates.
c. As a rule of thumb, use NOE when flying within the effective range of the threat weapon systems.
d. Use Contour when flying within 10 -15 Kilometers of the maximum effective range of the threat weapons systems.
e. Plan alternate ingress and egress flight routes.
f. Locate the SP 3 to 8 kilometers from the PZ’s. The flight route starts here.
g. Locate the RP 3 to 8 kilometers from the LZ’s, primary and alternate. The flight route ends here.
h. Use prominent, distinct terrain features located along the flight route that facilitates navigation, control of speed, and control of en route fires as ACPs.
i. Plan that no turn in the route exceeds 60 degrees, especially if slingloads are involved. j. Plan that routes are at least two kilometers wide.
k. Ensure the course to the RP is within 30 degrees of the final course and the final course is within 30 degrees of the LZ landing heading.

Q

What are the three modes of terrain flight as listed in the TC 3-04.4?

A

Nap of the Earth, Contour, Low-Level

NAP-OF-THE-EARTH FLIGHT

5-11. NOE flight is conducted at varying airspeeds as close to the earth’s surface as vegetation and obstacles permit. For NVG training, NOE flight is further defined as operating with the skids or wheels up to 25 feet above trees and vegetation in the flight path. (For training, a safe airspeed is used based on ambient light, flight visibility, terrain, winds, turbulence, obstacles, and crew proficiency.) Aviators should decrease airspeed if weather and/or ambient light restrict visibility.

CONTOUR FLIGHT

5-12. Contour flight is conducted at low altitudes conforming to the earth’s contours. It is characterized by relatively constant airspeeds and varying altitude as dictated by terrain and obstacles. For NVG training, contour flight is further defined as operating with the skids or wheels between 25 and 80 feet above highest obstacle (AHO). (For training, a safe airspeed is used based on ambient light, flight visibility, terrain, winds, turbulence, obstacles, and crew proficiency.) Aviators should decrease airspeed if weather and/or ambient light restrict visibility.

LOW-LEVEL FLIGHT

5-13. Aviators perform low-level flight at constant altitude and airspeed, dictated by threat avoidance. For NVG training, low-level flight is further defined as operating with the skids or wheels between 80 and 200 feet AHO at an airspeed commensurate with operational requirements and aircrew limitations. Aviators should decrease airspeed if weather and/or ambient light restrict visibility.

In reference to formation flight, what is sight picture and why must an aviator become proficient and comfortable with sight picture?

A

Sight picture is a particular angle, based on particular components a trailing aircraft sees or cues on when flying in formation on another aircraft. This is based on aircraft type and may cue on formation lights– especially at night or with NVDs. An aviator must become proficient and comfortable with this sight picture as it allows an aviator to judge attitude changes and relative position to the preceding aircraft.

(CAUTION)
Wires are nearly impossible to see with night vision devices (NVDs). They are also difficult to see during certain times of the day; for example, when an aviator is flying into a setting sun. Wires and poles can become coated in dust and snow making them even more difficult to identify. During any mission briefing, an aviator must review the presence of wires and identify the location and status of the wire-hazards map.

Q

What is the NOTE associated with the Storm Scope as written in current AWR1726? What is the CAUTION associated with Storm scope WX-500 operation, and how long is storm activity stored in the memory and displayed?

A

(NOTE)
The WX-500 Stormscope is susceptible to transmissions on the aircraft radios, and will intermittently present a false single lightning strike at the 7 o’clock position at approximately 40 nautical miles. This false strike will time out or the pilot may select”clear” on the MFD to remove.

(CAUTION)
Clusters of two or more discharge points in the strike display mode indicate thunderstorm activity when they reappear after clearing the screen. In the cell display mode, even a single discharge point may represent thunderstorm activity and should be avoided.

The stormscope memory can store up to 3600 individual strike or cell positions. The data is held in the memory for three minutes. After three minutes such expired data is deleted from the memory and the display.

131
Q

How does the Mechanical Mixing Unit compensate for torque effect and the vertical thrust component of the canted tail rotor?

133
Q

How do you create a storepoint and how many storepoints can be created?

A

Storepoints are created in flight and used for navigation or targets of opportunity. Store points maybe created by over flying a location and pressing MARK on the FLYOVER STORE screen by selecting a position on the map or by pressing the FIX key. Pressing the FIX key a second time will transition you to the STORE POINT DATA screen. The data conveyed here will be the location where the FIX key was first pressed and will be designated the next available letter designation. As many as 24 storepoints may be created, and will be designated as B through Z less O. Store point A is designated as the hover waypoint and is displayed on the PFD, ARC, HOVER and NAV displays.

134
Q

Why does the yellow EIC miscompare annunciation appear and what is the miscompare threshold for TGT?

A

The EICAS parameter values from the two DCUs are compared to detect possible faulty data. The comparison is always between DCU 1 and DCU 2 data, regardless of the selected EICAS data source for display. Due to processing of parameters separately by the DCUs, it is normal to see slight differences between the pilot and copilot EICAS readouts. Each DCU supplies both engine 1 and engine 2 data, but there is no comparison of engine 1 data to engine 2 data. When a miscompare condition is detected, the text label for the affected parameter turns to black text on a yellow background, and the yellow EIC miscompare annunciation appears above the PFD power pod.

135
Q

In reference to UH-60 ATM, what is the WARNING associated with Rolling Takeoff? Why should the aircraft’s heading be aligned with the take-off direction below maximum rate-of climb airspeed?

A

(WARNING)

If the takeoff is aborted, it may be impossible to stop the aircraft before clearing the barriers (depending on aircraft weight, speed, surface composition, and size of the takeoff area). Some situations requiring this maneuver will usually result in very marginal single engine characteristics. This increased risk factor will be addressed during the mission risk assessment process.

Maintain heading with pedals so the aircraft is aligned with the runway/surface takeoff direction when the aircraft is below maximum rate-of-climb airspeed should the takeoff need to be aborted.

136
Q

What does the Go Around (Go ARND) Mode provide, and how is it engaged? Can the pilot change FPM ROC and airspeed reference?

A

The GO ARND mode provides pitch, roll, collective cues, and FPS commands to establish a wings level 750 fpm Rate of Climb (ROC) while maintaining 70 knots. The GO ARND hold mode is manually engaged by pressing the GO ARND button on the corresponding FD/DCP. The GO ARND button on the cyclic grip also provides a means to manually select the GO ARND mode for engagement. GO ARND can be engaged at any airspeed.

The pilot cannot change the 750 fpm ROC and 70 knot airspeed references however, the pilot can at any time engage IAS or VS modes and adjust the desired airspeed or rate of climb.

137
Q

When is the LOC legend displayed on the FD/DCP? According to the student handout, when will BC be displayed on the FD/DCP?

A

Localizer - when a ILS localizer source is selected as the NAV source for the corresponding FD and when the difference between the selected course and the actual heading is less than 105°.

Back Course - (BC mode will ARM when the difference between the selected course and the actual heading is greater than 105°)

138
Q

What does the ILS DECL mode provide?

A

The ILS DECL provides a means to automatically decelerate the helicopter from its present airspeed to 70 knots prior to the 200-foot AGL point on the glide slope. Once the DECL mode achieves 70 knots, the IAS mode will automatically engage and the DECL mode will disen-gage. The airspeed for engagement of the DECL mode is 70 knots or greater.

139
Q

When can the VOR navigation mode be engaged?

A

The VOR navigation mode can only be engaged at indicated airspeeds of 50 knots and above. VOR can only be engaged when a valid VOR frequency is tuned and the FCC is receiving a VOR valid signal. The VOR mode is manually engaged by pressing the VOR button on the corresponding FD/DCP.

140
Q

When will the VOR mode switch to station passage mode? What happens during this mode?

A

When the FCC determines that the helicopter is over the VOR station. The CAP annunciation on the FD/DCP will change to SP to show the change in mode. The helicopter will stop attempting to track the VOR radial and will maintain the heading.

141
Q

While in the SP mode, when will the FD/DCP indicate VOR CAP again?

A

When the FCC determines the VOR signal has stabilized enough for navigation, the FD/DCP will indicate VOR CAP again; or if the FCC calculates the helicopter position approximately 3 miles from the VOR station,theFD/DCP should indicate VOR CAP again, whichever the FCC computes first.

142
Q

What is the difference between a sign of hypoxia and a symptom of hypoxia?

A

Signs are effects on the body can be observed by others and are therefore considered objective. However, individuals can observe or feel their own symptoms. Since symptoms can vary from person to person, they are considered subjective.

143
Q

What does the T in the triangle indicate in the margin data?

A

A black triangle with a white T, (appears in the notes area), signifies that the airport has nonstandard IFR takeoff minimums. The appropriate section in the front of the DOD FLIP (Terminal) charts is consulted in this case.

144
Q

The MSA for OZ (RUCKR) is 25 NM. What does this provide? Explain Minimum Sector and Emergency Safe Altitudes.

A

The MSA is provided for emergency purposes only and guarantees 1,000 feet obstruction clearance in the sector indicated with reference to the bearing in the circle. For conventional navigation systems, the MSA is normally based on the primary omnidirectional facility on which the IAP is predicated.

*** Altitudes depicted on approach charts which provide at least 1000 feet of obstacle clearance for emergency use within a specified distance from the navigation facility upon which a procedure is predicated. These altitudes will be identified as Minimum Sector Altitude or Emergency Safe Altitude and are established as follows:

(a) MINIMUM SECTOR ALTITUDES - Altitudes depicted on approach charts which provide at least 1,000 feet of obstacle clearance within a 25-mile radius of the navigation facility upon which the procedure is predicated. Sectors depicted on approach charts must be at least 90 degrees in scope. These altitudes are for emergency use only and do not necessarily assure acceptable navigational signal coverage.
(b) EMERGENCY SAFE ALTITUDES - Altitudes depicted on approach charts which provide at least 1,000 feet of obstacle clearance in non-mountainous areas and 2,000 feet of obstacle clearance in designated mountainous areas within a 100-mile radius of the navigational facility upon which the procedure is predicated and normally used only in military procedures. These altitudes are identified on published procedures as “Emergency Safe Altitudes”.

145
Q

Pressing left or right on the collective trim switch will result in what happening during cruise flight above 50 KIAS? What if that trim switch is adjusted up or down while in the Barometric Altitude Hold (ALT) Mode?

A

When HDG is not engaged with a coupled FD, the collective trim beeper may be used to establish a standard rate turn.

When using the collective trim beeper to increase or decrease altitude, the altitude will change at a rate of 4 fps for the first 4 seconds. After 5 seconds, the altitude will change at a rate of 16 fps. Holding the collective trim beeper up or down for more than 5 seconds changes the reference altitude by approximately 1000 fpm.

146
Q

What happens when the Emergency Control Panel, COM GUARD \ NORM switch is placed into the guard position? When the switch is returned to the NORM position what should happen?

A

COM GUARD:
Sets the COM 2 (AN/ARC-231 - 2) radio to 243.000 MHz (UHF guard frequency) and also sets the COM 3 (AN/ARC-231 - 3) radio to 121.500 MHz (VHF guard frequency)

NORM:
Placing the switch back to NORM sets both radios back to the previous band and frequency.

147
Q

How long after getting an immunization are crewmembers restricted from performing aircrew duties?

A

Medical restriction from flying duty will be for a minimum period of 12 hours following any immunization. If any type of reaction occurs, local or systemic, the aviator remains restricted from flying duties until cleared by a flight surgeon or APA.

148
Q

What two conditions must be present for the aircrew to fly below MDA or continue below the DH?

A

Descent below MDA is not authorized until sufficient visual reference with the runway environment has been established and the aircraft is in a position to execute a safe landing.

Descent below decision altitude/DH is not authorized until sufficient visual reference with the runway environment has been established.

149
Q

Above 50 KIAS, when the using the Indicated Airspeed (IAS) Hold Mode, what are two ways that the pilot can adjust the IAS reference for IAS hold?

A

By either using the P-Sync Knob or using the Cyclic Trim Beeper.

While the IAS mode is coupled, the IAS reference is capable of being adjusted five knots per second or in one knot increments upward by moving the cyclic TRIM beeper switch forward and downward by moving the cyclic TRIM beeper switch to the rear.

Q

You are enroute to Tallahassee on V7 airway 2 nautical miles from Seminole VORTAC, when Tallahassee approach control tells you the following: “Army 12345 hold at Seminole VORTAC”. This is the only information that you have received. What are you expected to do when arriving at the Seminole VORTAC?

A

If no holding pattern is charted and holding instructions have not been issued, the pilot should ask ATC for holding instructions prior to reaching the fix. This procedure will eliminate the possibility of an aircraft entering a holding pattern other than that desired by ATC. If unable to obtain holding instructions prior to reaching the fix (due to frequency congestion, stuck microphone, etc.), hold in a standard pattern on the course on which you approached the fix and request further clearance as soon as possible. In this event, the altitude/flight level of the aircraft at the clearance limit will be protected so that separation will be provided as required.

Q

What are the types of Hypoxia and their descriptions?

A

Hypoxic Hypoxia - Hypoxic hypoxia occurs when there is not enough oxygen in the air or when decreasing atmospheric pressure prevents diffusion of oxygen from the lungs to the bloodstream. high altitudes due to the reduction of PO2 in the atmosphere.

Hypemic Hypoxia - Hypemic, or anemic, hypoxia is caused by a reduction in blood’s oxygen-carrying capacity. Anemia and blood loss are the most common causes.

Stagnant Hypoxia - With stagnant hypoxia, blood’s oxygen-carrying capacity is adequate but circulation is inadequate. Conditions such as heart failure, arterial spasm, and blood vessel occlusion predispose affected individuals to stagnant hypoxia.

Histotoxic Hypoxia - Histotoxic hypoxia results from an interference with the use of oxygen by body tissues. Alcohol, narcotics, and certain poisons such as cyanide interfere with a cell’s ability.

164
Q

Performing a Z-axis plunge on the cyclic trim switch can be used for Unusual Attitude Recovery. What are the problems associated with using the Z-axis plunge to recover the aircraft?

A

Pressing in on the trim beeper switch is de-signed to recover the aircraft to a level flight attitude when above 60 KIAS, or command the aircraft to decelerate to a hover if below 60 KIAS. The effectiveness of the coupled flight director in recovering the aircraft to a level attitude or hover is dependant on the aircraft attitude and pitch/roll rate at the time the switch is pressed. The flight director is limited by the rate that the trim system can move the flight controls. There are combinations of extreme attitude and pitch/roll rates from which the flight director will not be able to recover to a level attitude/hover.

165
Q

How is the Vertical Speed (VS) Hold Mode selected? How do you change the VS reference?

A

VS mode is manually engaged by pressing the VS button on the corresponding FD/DCP.

Q

Why is Wiregrass VORTAC located on a concentric ring within the plan view?

A

Because they are Enroute Facilities

*** Dashed circles or concentric rings around the distance circle are used when the information necessary to the procedure will not fit to scale within the limits of the plan view area. They serve as a means to systematically arrange this information in its relative position outside and beyond the reference circle. These concentric rings are labeled en route and feeder facilities. The en route facilities ring depicts NAVAIDs, fixes, and intersections that are part of the en route low-altitude airway structure used in the approach procedure. The feeder facilities ring includes radio aids to navigation, fixes and intersections used by ATC to direct aircraft to intervening facilities/fixes between the en route structure, and the IAF. Feeder routes are not part of the en route structure.

195
Q

Additional reports- The following reports should be made at all times:

A
  1. When vacating any previously assigned altitude or flight level for a newly assigned altitude or flight level.
  2. When an altitude change will be made if operating on a clearance specifying “VFR ON TOP.”
  3. When unable to climb/descend at a rate of at least 500 feet per minute.
  4. When approach has been missed. (Request clearance for specific action; i.e., to alternative airport, another approach, etc.).
  5. Change in the average true airspeed (at cruising altitude) when it varies by 5 percent or 10 knots (whichever is greater) from that filed in the flight plan.
  6. The time and altitude or flight level upon reaching a holding fix or point to which cleared.
  7. When leaving any assigned holding fix or point.

NOTE: The reports in subparagraphs 6 and 7 may be omitted by pilots of aircraft involved in instrument training at military terminal area facilities when radar service is being provided.

  1. Any loss, in controlled airspace, of VOR, TACAN, ADF, low frequency navigation receiver capability, complete or partial loss of ILS receiver capability or impairment of air/ground communications capability. Reports should include aircraft identification, equipment affected, degree to which the capability to operate under IFR in the ATC system is impaired, and the nature and extent of assistance desired from ATC.

NOTE: Other equipment installed in an aircraft may effectively impair safety and/or the ability to operate under IFR. If such equipment (e.g. airborne weather radar) malfunctions and in the pilot’s judgment either safety or IFR capabilities are affected, reports should be made as above.

  1. Any information relating to the safety of flight.
    (b) When not in “radar contact”.
  2. When leaving final approach fix inbound on final approach (nonprecision approach) or when leaving the outer marker or fix used in lieu of the outer marker inbound on final approach (precision approach).

    (c) Pilots encountering weather conditions which have not been forecast, or hazardous conditions which have been forecast, are expected to forward a report of such weather to ATC.
196
Q

Define VFR-on-top versus VFR-over-the-top? According to AR 95-1, are there additional requirements for VFR-over-on-top?

A

VISUAL FLIGHT RULES-ON-TOP :

Aviators on IFR flight plans operating in VFR weather conditions may request VFR-On-Top in lieu of an assigned altitude. VFR-On-Top is an IFR clearance allowing aviators to fly VFR altitudes, which permits them to select an altitude or flight level of their choice (subject to any ATC restrictions).

VISUAL FLIGHT RULES OVER-THE-TOP :

VFR Over-The-Top is strictly a VFR operation in which the aviator maintains VFR cloud clearance requirements while operating on top of an undercast layer. This situation might occur when the departure airport and destination airport are reporting clear conditions, but a low overcast layer is present in between. The aviator could conduct a VFR departure, fly over the top of the undercast in VFR conditions, then complete a VFR descent and landing at the destination. VFR cloud clearance requirements are maintained at all times, and an IFR clearance is not required for any part of the flight.

95-1: Aircraft will not be flown above a cloud or fog layer under VFR for more than 30 minutes unless—

(1) The aircraft is equipped for IMC flight and not restricted from IMC flight.
(2) All IFR and requirements can be met for the remaining flight.

A

Anti-collision Light System, Position / Instrument Light(s), *Landing/Search Light, and Flashlight.

N. NVD IR light must be installed and operational for all NVD flights except FLIR aircraft. Failure of the light in flight must be evaluated to determine impact on mission and further NVD flight. Either the searchlight or landing light will suffice for the “white light” capability required for night operation.

204
Q

During tactical operations at night, how should the cockpit lighting be adjusted?

A

(CAUTION)

During tactical operations at night, cockpit lighting should be adjusted to the absolute lowest usable levels and crewmembers should be discrete in the use of supplemental lights to avoid detection by enemy forces.

205
Q

Referencing TC 3-04.4 Chapter 5, regarding terrain flight rally terms, such as ___________________________, and the use of clock positions to identify directions are typical terms used.

Q

If illumination is insufficient, how should an aviator perform a takeoff to ensure obstacle clearance?

A

If sufficient illumination does not exist, perform a Vertical takeoff by applying takeoff power first followed by a slow acceleration to ensure obstacle clearance. The P* may perform the takeoff from a hover or from the ground.

208
Q

In reference to UH-60 ATM, what are the NIGHT or NIGHT VISION GOGGLE (NVG) Considerations for TASK 1058: Perform VMC Approach?

A
  1. Altitude, apparent ground speed, and rate of closure are difficult to estimate at night. The rate of descent during the final 100 feet should be slightly less than during the day to avoid abrupt attitude changes at low altitudes. After establishing the descent during unaided flights, airspeed may be reduced to approximately 50 knots until apparent ground speed and rate of closure appear to be increasing. Progressively decrease the rate of descent and forward speed until termination of maneuver.
  2. Surrounding terrain or vegetation may decrease contrast and cause degraded depth perception during the approach. Before descending below obstacles, determine the need for artificial lighting. Use proper scanning techniques to avoid spatial disorientation.
  3. When performing operations during unaided night flight, ensure that the searchlight or landing light (white light) is in the desired position. Using the white light will impair night vision for several minutes. Therefore, exercise added caution when resuming flight before reaching full dark adaptation.
209
Q

The concept of __________________relates to how the cockpit layout design enhances the aviator’s ability to acquire information easily and quickly. It is the point the crew station designer specifies as where the aviator’s eyes would be.

211
Q

What physiological effects do smoking 3 cigarettes in rapid succession or 20 to 30 cigarettes within 24 hours before a flight have on a smoker’s night vision and physiological altitude?

A

The resulting physiological effects at sea level are the same as flying at 5,000 feet but, more importantly, the individual loses about 20 percent of his or her night vision capability.

212
Q

What is the difference between the night and day blind spot and how do we compensate for both?

A

Day blind spot:
Since humans have two eyes, they view all images with binocular vision. Each eye compensates for the day blind spot in the optic disk of the opposite eye. The day blind spot covers an area of 5.5 to 7.5 degrees and is located about 15 degrees from the fovea, originating where the optic nerve attaches to the retina. The size of the day blind spot is due to the optic nerve’s oval shape combined with its offset position where it attaches to the retina.
**No cones or rods are present at the attachment point. The day blind spot causes difficulty when individuals do not move their head or eyes but continue to look straight forward while an object is brought into the visual field. **
Figure 8-3, page 8-4, demonstrates the day blind spot.

Night blind spot:

The night blind spot (figure 8-7, page 8-6) should not be confused with the day blind spot. The night blind spot occurs when the fovea becomes inactive in low light conditions and involves an area from 5 to 10 degrees wide in the center of the visual field. An object viewed directly at night might not be seen due to the night blind spot; if the object is detected, it will fade away when stared at longer than 2 seconds. The size of the night blind spot increases as the distance between the eyes and object increases. Therefore, the night blind spot can hide larger objects as the distance between the observer and object increases. Figure 8-8 (page 8-6) illustrates this effect.

213
Q

How can night blind spot and the negative effects of scotopic vision be overcome?

A

Peripheral vision

Stimulation of only rod cells (peripheral vision most intact) is primary for viewing during scotopic vision. Crewmembers must use peripheral vision to overcome the effects of scotopic vision. Peripheral vision allows crewmembers to see dimly lit objects and maintain visual reference to moving objects.

214
Q

What is the CAUTION associated with the landing/search light?

A

Landing and searchlight have less than one foot ground clearance when extended. Use caution when taxiing over rough terrain when landing light and/or searchlight are extended.

215
Q

What is the off-center viewing technique?

A

There are no limitations to viewing an object with central vision during daylight. If this same technique is used at night, however, the viewer might not see the object due to the night blind spot that exists under low light illumination. To compensate for this limitation, crewmembers must use the off-center vision technique. This technique requires crewmembers to view an object by looking 10 degrees above, below, or to either side rather than directly at the object. The eyes maintain visual contact with the object via peripheral vision.

216
Q

What is the visual acuity of the human eye during day and night unaided viewing conditions?

A
Day = 20/20 
Night = 20/200 or less 
NVG = 100% Illumination 20/25 
NVG = 0% illumination = 20/70
217
Q

The average time required to gain the greatest sensitivity or adaptation to a dark environment is ________ minutes. When fully dark adapted the rod cells become up to _______ times more sensitive than at the start of the dark adaptation period.

A

30 to 45

10,000

218
Q

Describe how high and low flight altitudes affect terrain interpretation.

A

High Altitude:
Changes in viewing angle and distance at which an aviator is viewing an object will change the apparent shape of that object. The ability to identify manmade or natural features progressively decreases as flight altitude increases. This condition is affected at all levels of ambient light. When flight altitude increases, contrast between features becomes less distinguishable and features tend to blend. As terrain definition becomes less distinct, detection from altitude becomes difficult.

Low Altitude:
Terrain becomes more clearly defined and contrast is greater when an aviator flies closer to the ground. This allows manmade and natural features to be more easily recognized and permits increased navigational capability. However, the viewable area of a crewmember at low altitudes is smaller than at higher altitudes. With NOE/contour altitudes, that area is even smaller, sometimes requiring an aviator to reduce airspeed to permit more accurate terrain interpretation. Objects can also be identified at low altitudes by silhouetting them against the skyline.

219
Q

Effective scanning requires crewmembers to look from right to left or left to right. They should begin scanning at the __________ distance at which an object can be perceived (top) and move _________ toward the aircraft’s position (bottom).

A

greatest

inward

220
Q

These are examples of what type of scanning techniques? Why are we supposed to use these types of scanning techniques?

A

The retina’s low light vision elements are unable to perceive images in motion, so crewmembers should use a stop-turn-stop-turn scanning pattern to compensate.

221
Q

Define night myopia and what is Dark Focus?

A

NIGHT MYOPIA:
Blue wavelengths of light prevail in the visible portion of the spectrum at night. Therefore, slightly nearsighted or myopic individuals viewing blue-green light at night might experience blurred vision.

Dark Focus:
When light levels decrease, the eye’s focusing mechanism might move toward a resting position, making the eye more myopic.

222
Q

When operating in the ALL IR position for the exterior lights switch, what lights are disabled?

A

The anti collision lights, cargo hook light, normal position of the searchlight, and landing light are disabled in the ALL IR position.

223
Q

Describe the Effective Spatial Disorientation (SD) countermeasures?

A

Understand the risk factors; anticipate and plan for the preconditions before flight.

Employ good aircrew coordination. Pilots in command must establish a cockpit working environment that encourages announcement if an aircrew member is losing spatial orientation. Pilots in command must constantly monitor the factors conducive to the loss of orientation and manage the cockpit workload to prevent task saturation. Don’t keep two heads in the cockpit.

Assess the mission’s geographical environment, forecasted weather and night illumination, and takeoff, en route, and landing conditions where DVE operations are likely to occur.

Do not attempt visual flight below established weather minimums or in areas of deteriorating weather conditions.

Maintain proficiency in instrument flight with emphasis on aircraft control through the use of flight instruments. If appropriate, initiate prompt inadvertent IMC procedures.

Trust your instruments and make them read right.

In the event of suspected or recognized SD, reference instruments with a good cross check and attempt to ignore conflicting sensory inputs. (Note that some sensations are extremely powerful and difficult to override.) In two-pilot aircraft, announce SD and transfer the controls.

224
Q

IAW UH-60 ATM, If IMC is entered with the _______ ________ or ________ _______ on, SD may occur.

A

searchlight

landing light

225
Q

What is the primary means by which pilots maintain orientation? What factors are especially conducive to SD?

A

Vision—both ambient vision with position and motion cues, as well as focal vision for identifying flight parameters—is the primary means by which pilots maintain orientation.

However, the absence of a visible horizon (or false horizon) in combination with DVE and limited motion parallax cues is especially conducive to SD.

226
Q

Describe the terms EENT and BMNT:

A

Ambient solar light is usable for a period following sunset and before sunrise. After sunset, the amount of available solar light steadily decreases until the level of light is not usable to the unaided eye. Solar ambient light becomes unusable when the sun is 12 degrees below the horizon or about 48 minutes after sunset. This is end evening nautical twilight (EENT). Before sunrise, solar light becomes usable when the rising sun is 12 degrees below the horizon or about 48 minutes before sunrise, which is begin morning nautical twilight (BMNT).

227
Q

Referencing the FAR/AIM, describe the colors and color combinations of airport, heliport and military airport beacons:

A
  1. White and Green− Lighted land airport.
  2. *Green alone− Lighted land airport.
  3. White and Yellow− Lighted water airport.
  4. *Yellow alone− Lighted water airport.
  5. Green, Yellow, and White− Lighted heliport.

NOTE− *Green alone or yellow alone is used only in connection with a white−and−green or white−and−yellow beacon display, respectively.

Military airport beacons flash alternately white and green, but are differentiated from civil beacons by dualpeaked (two quick) white flashes between the green flashes.

228
Q

What are your VFR weather minimums at night above and below 1200’ but less than 10,000 MSL in Class G and E airspace?

A

Class E = Less than 10,000 feet MSL

3 statute miles 500 feet below
1,000 feet above
2,000 feet horizontal

G (Rotary Wing) – more than 1,200 ft above surface but less than 10,000 ft MSL

Night 3 Statute Miles 500 ft below
1,000 ft above
2,000 ft horizontal

G (Rotary Wing) – 1,200 ft or less above surface (regardless of MSL)

Night 1 Statute Miles Clear of clouds

229
Q

Describe the factor that aids in determining distance using the retinal image: Known size of objects

A

A structure projects a specific angle on the retina based on its distance from the observer. If the angle is small, the observer judges the structure to be a great distance away, while a larger angle indicates the structure is close.

***To use this cue, the observer must know the object’s actual size and have prior visual experience with it. If no experience exists, the observer determines the distance to an object primarily by motion parallax

230
Q

Describe the factor that aids in determining distance using the retinal image: Increasing or decreasing size of objects

A

If the retinal image of an object increases in size, the object is moving closer to the observer. If the retinal image decreases, the object is moving further away. If the retinal image is constant, the object is at a fixed distance.

231
Q

Describe the factor that aids in determining distance using the retinal image: Terrestrial Association

A

Comparison of one object such as an airfield with another object of known size such as a helicopter helps in determining the relative size and apparent distance of the object from the observer.

232
Q

Describe the factor that aids in determining distance using the retinal image: Overlapping Contours or Interposition of Objects

A

When objects overlap, the overlapped object is further away. For example, an object partially concealed by another object is behind the object concealing it. Crewmembers must be especially conscious of this cue when making an approach for landing at night. Lights disappearing or flickering in the landing area should be treated as barriers and the flight path adjusted accordingly.

233
Q

Describe the factor that aids in determining distance using the aerial perspective: Fading of Colors or Shades

A

An object viewed through haze, fog, or smoke appears less distinct and at a greater distance than it actually is. Conversely, if atmospheric transmission of light is unrestricted, the object appears more distinct and closer than it actually is.

234
Q

Describe the factor that aids in determining distance using the aerial perspective: Loss of detail or texture

A

The further an observer is from an object, the less apparent discrete details become. For example, at a distance a cornfield appears to be a solid color, tree leaves and branches appear to be a solid mass, and objects appear to be at a great distance.

235
Q

Describe the factor that aids in determining distance using the aerial perspective: Position of Light Source and Direction of Shadow

A

Every object casts a shadow in the presence of a light source. The direction in which the shadow is cast depends on the position of the light source. If an object’s shadow is cast toward an observer, the object is closer to the observer than the light source.

236
Q

Describe the monocular cue: Motion parallax.

A

Motion parallax is often considered the most important depth perception cue. Motion parallax refers to the apparent relative motion of stationary objects as viewed by an observer moving across the landscape. Near objects appear to move past or opposite the path of motion; far objects appear to move in the direction of motion or remain fixed. The rate of apparent movement depends on the distance the observer is from the object. Objects near an aircraft appear to move rapidly, while distant objects appear to be almost stationary.

237
Q

What is an operational defect? Operational defects include:

A

Operational Defects
These defects relate to the reliability of the image intensifier and are an indication of instability. If identified, they are an immediate cause for rejecting the ANVIS.

They include Shading, Edge Glow, Flashing, Flickering, Intermittent Operation and Emission Points.

238
Q

Describe how exposure to bright sunlight can have a cumulative and adverse effect on dark adaptation.

A

Exposure to bright sunlight also has a cumulative and adverse effect on dark adaptation. Reflective surfaces such as sand, snow, water, and manmade structures intensify this condition. Exposure to intense sunlight for 2 to 5 hours decreases visual sensitivity for up to 5 hours and also decreases the rate of dark adaptation and degree of night visual acuity. These cumulative effects can persist for several days.

239
Q

Describe the protective measures that can be taken to preserve an aviator’s night vision.

A

COCKPIT LIGHT ADJUSTMENT

Instrument, cockpit, and rear cargo area overhead lights should be adjusted to the lowest readable level that allows instruments, charts, and maps to be interpreted without prolonged staring or exposure.

EXTERIOR LIGHT ADJUSTMENT

If possible, exterior lights should be dimmed or turned off, mission permitting. Aviators should consult command policy for local procedures.

LIGHT FLASH COMPENSATION

The pilot should turn the aircraft away from a light source if a high-intensity flash is expected from a specific direction.

240
Q

Explain binocular cues and their value to crewmembers?

A

Binocular cues depend on the slightly different view each eye has of an object. Thus, binocular perception is of value only when the object is close enough to make a perceptible difference in the viewing angle of both eyes. However, since most distances outside the cockpit are so great, binocular cues are of little to no value to crew members.

241
Q

What are the monocular cues that can assist crewmembers with distance estimation and depth perception?

A

Several monocular cues assist crewmembers with distance estimation and depth perception. These cues are geometric perspective, retinal image size, aerial perspective, and motion parallax.

(GRAM)

242
Q

Describe the type of geometric perspective: Linear perspective

A

Parallel lines such as railroad tracks tend to converge as distance from the observer increases.

243
Q

Describe the type of geometric perspective: Apparent foreshortening

A

The shape of an object or terrain feature appears elliptical (oval and narrow) when viewed from a distance at both higher and lower altitudes. As the distance to the object or terrain feature decreases, the apparent perspective changes to its true shape or form.

244
Q

Why is terrain interpretation more difficult when the moon is low on the horizon?

A

Terrain interpretation is more difficult when the moon is low on the horizon. This is due to the lower light level and the shadows caused by the low angle. If low-level flight is conducted toward the moon, with the moon at a low angle, glare may bother the aircrew causing distorted vision and a loss of dark adaptation. During aided flight, glare may also degrade NVD capability. However when the moon is low on the horizon, terrain features or objects on the skyline are more recognizable.

245
Q

What factors affect the quality of depth perception and distance estimation while using NVGs?

A

factors including available light, type and quality of NVG, degree of contrast in the FOV, and user experience. The aircrew must often rely on monocular cues.

246
Q

How can crewmembers compensate for the loss of peripheral vision while wearing NVGs?

A

An NVG’s FOV significantly reduces peripheral vision as compared with unaided flight. Crewmembers must use a continual scanning pattern to compensate for the loss. Moving the eyes will not change the viewing perspective; the head must be turned. Rapid head movement, however, can induce spatial disorientation. To view an area while using NVG, a crewmember’s head and eyes must rotate slowly and continuously. The length of time and frequency of the scanning pattern is based on the type of terrain and obstacles, airspeed, and what is actually seen through the NVG. When scanning to the right, crewmembers should move their eyes slowly from the left limit of vision inside the device to the right limit while moving their head to the right. This enables a crewmember to cover a 70- to 80-degree FOV with only 30 to 40 degrees of head movement, minimizing head rotation. The crewmember should scan back to the left in reverse order avoiding rapid head movements.

247
Q

How is spatial disorientation affected by wearing NVGs?

A

Maneuvers requiring large bank angles or rapid attitude changes tend to induce spatial disorientation. An aviator should avoid making drastic changes in attitude/bank angles and use proper scanning and viewing techniques.

248
Q

Explain the term cosmetic blemish. If you believe a cosmetic blemish is cause for rejection how should you record the problem on the maintenance form?

A

These are usually the result of manufacturing imperfections that do not affect image intensifier reliability and are not normally a cause for rejecting an ANVIS. However, some types of blemishes can get worse over time and interfere with the ability to perform the mission. If you believe a blemish is cause for rejection, record the specific nature of the problem on the maintenance forms and identify the position of the blemish by using the clock method and approximate distance from the center (e.g., 5 o’clock toward the outside, 2:30 near the center, or 1:00 midway).

249
Q

What are the HUD systems designed to do? Which enables aviators to do what?

A

HUD systems are designed to display flight, navigation, and aircraft system information onto the NVG display. It enables an aviator to concentrate his or her vision outside the cockpit while maintaining the ability to view critical information.

250
Q

WARNING: Failure to remove the ANVIS neck cord prior to operation of the HUD may _____________ from the aircraft in an __________.

Q

The Display Unit (LCD) will only operate on aircraft having the ____________.

A

Mini Signal Data Converter (SDC)

255
Q

List the ANVIS/HUD fail messages, system messages and sensor warning messages. Where are they displayed?

A

Fail Messages: PSG, PS, PDU, CPDU, NAV (NAV indicates a comm fail between HUD and Navigation information. (PGM will be displayed when other operator is Programming their symbology set but this is NOT a Fail Message)

System Messages: MST (Master Caution), HOOK (Cargo Hook Open)

Sensor Warning Messages: ENG1 / ENG2 (Engine Out), Fire (Fire Warning), RPM (Low Rotor RPM) ***Messages are displayed in the bottom center of the HUD

256
Q

How many HUD display modes can be programmed?

A

Up to eight display modes, four normal and four declutter, can by programmed for each user and can be selected for display using the display mode selection switch on the pilot’s collective control.

257
Q

According to the TM 11-5855-313-10, what meteorological and lighting conditions can reduce the effectiveness of the ANVIS?

A

The equipment requires some ambient light (moonlight, starlight, etc.) to operate. Ambient light is reduced by such factors as passing cloud cover and objects that produce shadows.

Low-contrast environments (such as snow-covered territory sandy deserts, large bodies of water, or grassy hills) degrade visibility, thereby making it difficult to distinguish features of the terrain. In these environments, ANVIS visual acuity can deteriorate to 20/200 or worse.

ANVIS may experience a measurable loss of performance at temperatures above 100°F (38°C).

258
Q

If there is more than one flicker, what should you check before rejecting the goggles for flashing, flickering or intermittent operation?

A

check for loose wires, loose battery cap/door, or weak batteries.

259
Q

To be considered night vision goggles (NVG) current, a crewmember must take part every _______ in at least a ______ flight in the aircraft at night while wearing NVG. NVG currency may be accomplished within any H-60 series in which qualified and current. A RCM must be at a crew station with access to the__________.

A

60 days

one-hour

flight controls

(TC 3-04.11)

260
Q

What is the minimum symbology that will be displayed in the declutter mode of operation?

A

airspeed, altitude (MSL), attitude (pitch and roll), and engine torque(s)

261
Q

How do you get to the programming and control page of the NVG HUD on the FMS?

A

MSN - ffk
NVG HUD CONTROL PAGE- SK
PGM MODE- SK

262
Q

Discuss the following functions on the HUD page of the FMS.

a. DSPL POS COPILOT OFF/ON –
b. PGM MODE OFF/PLT/CPLT –

NOTE: Only the P or P* that is selected during program mode can make changes at that time.

c. MFD SOURCE PLT/CPLT –
d. DSPL POS PILOT OFF/ON –
e. UP –
f. DOWN –
g. DECLUTTER LEVEL –
h. RTN –

A

A. Allows the copilot to adjust the position of the HUD display symbology. When set to ON, the HUD collective grip switch will adjust the position of the image on the copilot’s HUD display. The directions of movement are left, right, up, and down. Default is OFF.

B. Sets the programming mode to OFF/PLT/CPLT. Default is OFF. When the pilot or copilot programmingmodeisON,theHUD collective grip switch programs the PLT and CPT pages, and declutter modes.

C. Selects the data source for HUD symbology. The default is PLT, meaning the BC FMS will send the display information to the HUD from one of the pilot side MFDs. When one MFD fails, or is switched OFF, the FMS automatically selects the other MFD on that side of the aircraft. If both MFDs on the source side fail, or are switched OFF, the pilot must use the FMS data source soft key to switch the source from one side of the aircraft to the other. This prevents the operator’s display from switching data sources without notification, as the HUD provides no display of data source.

D. Allows the pilot to adjust the position of the HUD display symbology. When set to ON, the HUD collective grip switch will adjust the position of the image on the pilot’s HUD display. The directions of movement are left, right, up, and down. Default is OFF.

E. Increments the HUD display page number. The indication of page number is not displayed on this screen, it is displayed on the HUD display symbology only. This works on a per-side basis when accessed on the copilot’s FMS, the soft key operates the copilot’s HUD display, and when accessed on the pilot’s FMS the soft key operates the pilots HUD display.

F. Decrements the HUD display page number. Functions the same way as the UP soft key.

G. Increments the declutter level of the selected HUD screen. Each depression of this soft key toggles the HUD declutter level between two positions: normal, and declutter. The declutter level is indicated on the HUD display symbology. This soft key also works on a per-side basis.

H. Returns to the MISSION SYSTEMS page.

263
Q

Discuss the following functions of the collective HUD controls.

A

PG UP: Increments the HUD display page number.

BRT: Increases HUD brightness.

DCLT: Increments the declutter level of the selected HUD screen.

PG DN: Decrements the HUD display page number.

DIM: Decreases HUD brightness.

264
Q

Describe the type of geometric perspective: Vertical position in the field

A

Objects or terrain features at greater distances from the observer appear higher on the horizon than those closer to the observer.

Before flight, crewmembers should already be familiar with the actual sizes, heights, and altitudes of known objects or terrain features within and around the planned flight route. If the situation and time permit, crewmembers can reference published information to verify actual sizes and heights of objects and terrain features within their flight path. In addition, crewmembers should cross-reference the aircraft altitude indicator to confirm actual aircraft altitude is adequate to safely negotiate the object or terrain feature without prematurely changing aircraft heading, altitude, attitude, or a combination thereof.

265
Q

Describe autokinesis and how to compensate for it.

A

Autokinesis occurs primarily at night when ambient visual cues are minimal and a small, dim light is seen against a dark background. After about 6 to 12 seconds of visually fixating on the light, an individual may perceive movement at up to 20 degrees in any particular direction or in several directions in succession, although there is no actual object displacement. This illusion can cause a pilot to mistake the fixated object for an object in motion (such as, another aircraft). In addition, a pilot flying at night might perceive a relatively stable lead aircraft to be moving erratically when, in fact, it is not. The unnecessary and undesirable control inputs the pilot makes to compensate for the illusory movement result in increased workload and wasted motion at best and an operational hazard at worst.

*** - Occurs at night when ambient cues are minimal when a small dim light is seen against a dark background. After 6-12 seconds of fixating on the light it will perceive to move 20 degrees in any particular direction, although there is no actual movement.
- Can cause erratic and unnecessary control inputs to try and compensate for the movement, best case is unnecessary workload, worst case causes operation hazard.
- experience, be familiar with the illusion and confirm what you are seeing with your crew.

266
Q

Explain when photopic vision is experienced and its characteristics.

A

Experienced during daylight or under high levels of artificial illumination. Cones concentrated in the fovea centralis are primarily responsible for vision in bright light. Due to the high-level light condition, rod cells are bleached out and become less effective. Sharp image interpretation and color vision are characteristics of photopic vision. The fovea centralis is automatically directed toward an object by a visual fixation reflex. Therefore, under photopic conditions, the eye uses central vision for interpretation, especially in determining details.

*** - Experienced during daylight or under high levels of artificial illumination
- Cones in the fovea centralis are primarily responsible for vision in bright light. Due to light levels rods are bleached out and less effective.
- Characterized by sharp image interpretation and color vision.

267
Q

Explain when mesopic vision is experienced and its characteristics.

A

Experienced at dawn, dusk, and under full moonlight. Vision is achieved by a combination of rods and cones. Visual acuity steadily decreases with declining light. Color vision is reduced or degraded as light levels decrease and the cones become less effective. Mesopic vision is the most dangerous vision type for crewmembers. How degraded the ambient light condition is determines what type of scanning or viewing technique crewmembers should use to detect objects and maintain safe and incident-free flight. For example, the gradual loss of cone sensitivity might necessitate off-center viewing to detect objects in and around the flight path. Incidents might occur if crewmembers fail to recognize the need to change scanning techniques from central or focal viewing to off-center viewing.

*** - Dawn, Dusk under full moon light, vision is achieved by rods and cones.
- Steadily reduced visual acuity as light levels decline. Color vision is reduced or degraded as light decreases and cones become less effective.

268
Q

Explain when scotopic vision is experienced and its characteristics.

A

Experienced in low light environments such as partial moonlight and starlight conditions. Cones become ineffective in these conditions, causing poor resolution in detail. Visual acuity decreases to 20/200 or less, and color perception is lost. A central or night blind spot occurs when cone cell sensitivity is lost. Scotopic vision degrades primary color perception to shades of black, gray, and white unless the light source is of adequate intensity to stimulate the cones. Peripheral vision is used primarily while viewing with scotopic vision.

*** - low light enviroments such as partial moon and starlight conditions. Cones become ineffective causing poor resolution in detail.
- Visual Acuity decreases to 20/200 or less and color perception is lost. Night blind spot occurs due to no cones in the fovea. Peripheral vision is the primary viewing sector during scotopic conditions.

269
Q

Of the three types of vision, which is the most dangerous and why?

A

Mesopic vision is the most dangerous vision type for crewmembers.

Scanning/ viewing techniques are determined by light levels, failure to recognize a need to change scanning techniques can cause crew to miss an object or terrain causing accidents.

270
Q

Describe the false horizon illusion and how to compensate for it.

A

False horizon illusions occur when a pilot confuses a wide sloping plane of reference such as sloping cloud tops, mountain ridges, or so-called ‘cultural’ lighting at night (such as a coastline or highway) with the true horizontal (figure 9-11). A sloping cloud deck, for example, can be difficult to perceive as anything but horizontal if it extends any great distance in the pilot’s peripheral vision. The pilot might perceive the cloudbank to be horizontal even if it is not horizontal to the ground, and position the aircraft into a banked attitude thinking it is level. This condition is often insidious and may go undetected until the pilot recognizes it via cueing to instruments and makes necessary corrections. This illusion may also occur if the pilot looks outside after having given prolonged attention to a task inside the cockpit. Confusion can result in the pilot incorrectly placing the aircraft “level” according to the sloping cloudbank.

*** -when pilot confuses cloud formations with the horizon or ground. Usually occurs when cloud banks are sloping and continue for a some distance. Pilot gets focused inside and when he transfers back out mistakes the clouds for the ground.
- Compensate - Difficult to perceive and goes undetected until the pilot recognizes it, transitions to instruments, and makes necessary corrections.

271
Q

Describe the fascination (fixation) and how to compensate for it.

A

While not a visual illusion, per se, this can be just as deadly. Fascination or fixation in flying can be separated into two categories: task saturation and target fixation. Task saturation occurs when crewmembers become so engrossed with a problem or task within the cockpit that they fail to properly scan outside the aircraft. Target fixation, commonly referred to as target hypnosis, occurs when crewmembers ignore orientation cues and focus their attention on an object or goal. For example, an attack pilot on a gunnery range might become so intent on hitting a target that he or she forgets to fly the aircraft, causing it to strike the ground, target, or shrapnel.

*** Fascination (inside)- Task Saturation- so engrossed with problem in cockpit they fail to properly scan outside.
Fixation (outside)- Target Fixation( ignore orientation cues and focus on an objective or target)

Compensate- Recognition and always maintaining proper scan inside the aircraft and out.

272
Q

Describe size constancy in regards to size distance illusion.

A

A common example of a size constancy illusion is that of landing at an unfamiliar runway (figure 9-13). A runway that is narrower than expected may cause the pilot to think he or she is higher and further away resulting in the flying of the approach too low and land short. Likewise a wider runway than expected may cause the pilot erroneously to think he or she is closer resulting in flying the approach too high and land long.

273
Q

Describe confusion with ground lights and how to compensate for it.

A

A related illusion, confusion with ground lights, occurs when a pilot mistakes ground lights for stars. The illusion prompts the pilot to place the aircraft in an unusual attitude to keep the misperceived ground lights above the aircraft. Isolated ground lights can appear as celestial lights, which could lead to the illusion the aircraft is in a nose-high or one-wing-low attitude (figure 9-12, part A; page 9-12). When no celestial lights are visible because of overcast conditions, unlighted terrain can blend with the dark overcast to create the illusion the unlighted terrain is part of the sky (figure 9-12, part B; page 9-12). This illusion can be avoided by referencing the flight instruments and establishing true horizon and attitude.

*** -Pilot mistakes ground lights for celestial lights. Illusion prompts pilot to place the aircraft in an unusual attitude to keep the misperceived ground lights above the aircraft.
- Compensate- avoided by referencing the flight instruments and establishing true horizon and attitude.

274
Q

Describe the height and depth perception and how to compensate for it.

A

Height-depth perception illusions are due to absent or insufficient visual cues and cause crewmembers to misjudge depth perception. Flying over areas devoid of visual references such as desert terrain, snow, or water may deprive crewmembers of their perception of height. Misjudging the aircraft’s true altitude, the pilot might fly the aircraft dangerously low to the ground or other obstacles above the ground. Flight in an area where visibility is restricted by misty rain, fog, smoke, whiteout, brownout, or haze can produce the same illusion.

*** - due to lack of sufficient visual cues causes crew members to lose their depth perception. Brownouts, whiteouts, smoke, and fog can also cause lack of height depth.
-compensate- Avoid by referencing your instruments specifically Altimeters

275
Q

Describe the size and distance illusion and how to compensate for it.

A

Size and shape constancy are important when a familiar object’s known size and shape is used to judge its distance from the observer. Size-distance misperceptions give rise to a number of related illusions whereby a crewmember misinterprets an object of unfamiliar size and shape by comparing it with what they are accustomed or familiar to seeing based on experience.

*** - false perceptions of distance from an object or the ground, created when a crewmember misinterprets unfamiliar objects size with something they are familiar with.(e.g. making approach in Washington state avg tree 100ft, as opposed to ft rucker avg tree 30 feet)
- Compensate- be familiar with your flight route and where your are going and always cross check instruments

276
Q

In regards to size distance illusion, describe shape constancy while viewing sloping runways.

A

A related illusion is that of shape constancy which is commonly encountered with sloping runways (figure 9-14). A typical glideslope to landing of 3 to 4 degrees is such that only a one degree change in runway slope can affect the landing sight picture. With the shape constancy illusion, the foreshortened picture of an up sloping runway may give the pilot the illusion of being too high. A natural tendency is for the pilot to want to ‘reshape’ the sight picture resulting in flying the approach too low. The reverse is true for a down sloping runway. In both cases, being forewarned of the potential hazard with good pre-mission planning and cross-checking the visual VASI or PAPI lights would be important.

277
Q

Describe the Induced motion illusion and how to compensate for it.

A

Induced motion is falsely perceived motion of oneself when no physical motion is actually occurring. The most common example is vection—visually induced perception of self-motion. Consider the example of an individual in a car stopped at a traffic light and another car slowly pulls alongside. The individual stopped at the light may perceive the other car’s forward motion as his or her own rearward motion, resulting in the individual suddenly applying additional pressure to the brakes. Another common example is that of two adjacent trains whereby a passenger on one misperceives self-motion due to the movement of the other train. This illusion can be encountered during flight in situations such as formation flight, hover taxi, or hovering over moving water, blowing snow or dust, or movement of tall grass.

***-Falsely perceived self motion in relation to another objects motion.
-Compensate- with solid cross check of instruments.

Q

What is the purpose of the minus blue coating on the NVG’s?

A

A special coating in the objective lens of the ANVIS that filters out light from the instrument panel in aircraft with the correct lighting. This makes the ANVIS “blind” to the instrument lighting so the glare does not interfere with viewing outside the aircraft.

***A special coating that reduces interference from the instrument panel and NVG-compatible supplemental cockpit lights. It makes the ANVIS “blind” to the lighting so the glare does not interfere with viewing outside the aircraft.

279
Q

How can you determine if your flashlight or other supplemental lighting (lip lights, finger lights etc.) are compatible with NVGs?

A

Supplemental Lighting Degradation Check

The check must be conducted at night, in an aircraft located in an area of low ambient light, such as an LZ, with interior lighting set for NVG operations, and with ANVIS prepared for use.

  1. Position a reflective material (map sheet, note card, vinyl checklist) approximately 12 to 18 inches from the eyes.
  2. Shine the supplemental light onto the material.
  3. With the unaided eye, look at the resultant reflection cast on the windscreen. Observe this same reflection through the ANVIS. An acceptable supplemental light source will not interfere with the operator’s ability to see outside the aircraft using NVGs. The reflection of the light source in the windscreen may even disappear. If the reflection, glare, or stray light interferes with the ANVIS aided vision of any crewmember the light source is unacceptable.
280
Q

Define scintillation.

A

A faint, random, sparkling effect throughout the image area. Scintillation is a normal characteristic of the image intensifier assembly and should not be confused with emission points. Scintillation is more pronounced under low light conditions. Sometimes called ”video noise.”

281
Q

Describe the structural illusion and how to compensate for it.

A

Structural illusions are caused by the effects of rain, snow, sleet, heat waves, or other visual obscurants. A straight line can appear curved when viewed through heat waves in the desert. A single wingtip light might appear as a double light or in a different location when viewed through rain. Curvature of the aircraft windscreen also can cause structural illusions due to the refraction of light rays as they pass through the windscreen. Pilots must remain vigilant to the potential for false perceptions when operating in environments containing these obscurants.

*** - Caused by effects of heat waves, rain, snow, sleet or other visual obscuration. Straight line seems curved when seen through heat rays in desert.
Curvature of the A/C windscreen also causes it due to refraction of light rays as they pass through the windscreen.
- Compensate- Experience and Knowlege

282
Q

Describe aerial perspective in relation to size distance illusion.

A

Another size-distance illusion is that of aerial perspective. These illusions can occur if visual cues are of a different size or perspicuity (clarity and discrimination) than expected. A classic example would be for a pilot to mistake immature, short or stunted trees for large, tall ones causing him or her to misjudge altitude above the ground. A different but somewhat related phenomenon may occur in rain, smoke or haze, whereby a pilot may erroneously think that the lights of another aircraft or runway approach lighting to be much farther away than actual distance due to lack of brightness and clarity. Objects viewed within a hazy environment, for example, are often thought to be further away.

283
Q

Describe the crater illusion and how to compensate for it.

A

Crater illusions occur when crewmembers land at night under night vision device conditions and the infrared searchlight is directed too far under the aircraft’s nose. This combination creates the illusion of landing with up sloping terrain in all directions or landing in a crater. This illusionary depression lulls the pilot into continually lowering the collective and could result in the aircraft prematurely impacting the ground. If observing another aircraft during hover taxi, the pilot might perceive the crater is moving with the aircraft being observed.

*** - When crew members land at night under NVD conditions and the IR searchlight is too far under the nose. This will cause an illusion of landing upslope .
- Compensate- Proper scanning and proper use of the landing and search lights.

284
Q

After practicing VMC approaches to Stinson, you transition over to Cairns AAF, and perform a VMC approach. Your IP tells you that your approach at Cairns was much too high and steep, even though it seemed identical to the approaches you made at Stinson. Which visual illusion are you experiencing, and why is this occurring?

A

Size Distance illusion. The size/ length of the runway is different from cairns to Stinson.

286
Q

What is an emission point?

A

A steady or fluctuating pinpoint of bright light in the image area that does not go away when all light is blocked from the objective lens of that monocular.

The position of an emission point within the image area of the monocular does not move. An emission point should not be confused with a point light source in the distance.

287
Q

What is edge glow, what causes it and how do you check for it?

A

Edge glow is a bright area (sometimes sparkling) in the outer portion of the viewing area.

caused by an emission point (or series of emission points) just outside the field-of-view or by a defective phosphor screen that permits light feedback to the photocathode.

To check for edge glow, block out all light by cupping a hand over the lens. If the image tube is displaying edge glow the bright area will still show up.

288
Q

Explain shading. Which cosmetic blemish should it not be confused with? Describe the two other items as explained in the note (same page) it should not be confused with?

A

If shading is present, you will not see a fully circular image. Shading is indicative of a dying photocathode caused by a defective vacuum seal of the image intensifier. Shading always begins on the edge and migrates inward eventually across the entire image area.

Do not confuse shading with variations in output brightness. Make sure the shading is not the result of improper adjustment and lens caps are not installed.

289
Q

291
Q

What are the differences between Rods and Cone cells? Where are they located in the Retina?

A

Rods- Used for night vision (low intensity light vision) 10,000 rods per nerve located in periphery primarily. Responsible for Night (Scotopic) Vision. The concentration of rod cells begins to increase toward the retina’s periphery.

Cones- used for day or high intensity light vision (viewing periods or conditions) 1 cone per nerve located in fovea and para fovea and responsible for color vision and shading (black, grey, white in low light levels). The center of the retina, the fovea, contains a very high concentration of cone cells but no rod cells.

292
Q

How do NVGs affect an aviator’s ability to detect deteriorating weather, and what cues can be used to recognize them?

A

When using NVG, aviators may fail to detect entry into or presence of IMC. NVG enable crewmembers to see through obscurations, such as fog, rain, haze, dust, and smoke, depending on density. As density increases, aircrews can detect a gradual reduction in visual acuity as less light is available.

The apparent increase in size and density of halos during bad weather is an illusion.

While contrast decreases, video noise may increase. There may be a loss of celestial lights, while the moon and stars may fade or disappear due to overcast conditions.

Cues to look for light dimming, increase in halos, scintillation increase, loss of celestial lights.

293
Q

Explain how the changes in illumination percentages effect the visual acuity of the ANVIS and what is more pronounced with the reductions of illumination percentages.

A

Visual acuity maximizes at 100% illumination (full moon conditions), degrading steadily until available illumination reaches approximately 50%, or ½ moon.

As illumination drops below 50%, visual acuity degrades more rapidly, causing the halo effect around light sources to be more pronounced.

As illumination levels drop below 25-30% scintillation becomes more apparent. Visual acuity is at its lowest at 0% illumination (starlight conditions), with a fully overcast sky, and no cultural (man-made)sources of illumination.

visual acuity under standard 100% illumination and a high-contrast environment) approaches 20/25 as described above. 0% illumination, with overcast skies and no cultural lighting) ANVIS visual acuity is approximately 20/70.

294
Q

How can the use of lasers affect an aviator’s night vision capabilities?

A

The eye is more vulnerable to laser damage at night as the iris of the eye opens more to accommodate lower levels of illumination. Laser damage to the eyes includes flash blindness, minor and major retinal burns, and impaired night vision.

295
Q

_____________ might be experienced when the eyes attempt to simultaneously perceive two dissimilar objects independently. This phenomenon can occur when pilots view objects through the headsup display. Conflict in total perception arises when one eye views one image and the other eye views another image. Quite often, the dominant eye overrides the nondominant eye, possibly causing information delivered to the nondominant eye to be missed.

A

Retinal rivalry

296
Q

What is a zero time battery and where is it placed in your battery pack for NVG’s?

A

Alternate batteries. These are zero-time batteries used as a backup to the primary batteries. They are inserted in the battery compartment of the power pack that is on the wearer’s left side.

297
Q

According to current AWR 1726, what are the WARNINGs and NOTE regarding the position lights?

A

Warning- OXLEY When flying in close proximity formation flight, the position
lights are extremely bright and create a “halo” effect around the
aircraft. This halo effect makes it extremely difficult to see the
preceding aircraft in formation flight.

Warning- OXLEY The IR position light is mounted on the right side of the tail
position light. In this position, aircraft flying staggered left formation
flight cannot see the IR position light.

NOTE
OXLEY The bright and dim switch does not change the intensity of
the lights.

298
Q

The five basic subsystems of AFCS are?

A

Stability Augmentation System (SAS) – provides short-term rate dampening in pitch, roll, and yaw axis.

Trim – provides control positioning and force gradient functions.

FPS – basic autopilot functions when coupled with trim.

Coupled Flight Director – provides a means for the pilot to select defined autopilot functions, automatic flight control positioning, and provides steering cues for display on the MFD when coupled.

Stabilator – improves flying qualities with the use of electromechanical actuators in response to collective, airspeed, pitch rate, and lateral acceleration inputs.

299
Q

Some crewmembers may experience a pink, brown, or purple afterimage when they remove NVGs. This normal physiological phenomenon is called?

A

Color discrimination is absent when a crewmember views scenes through NVG. The picture viewed is monochromatic (single color) and has a green hue due to the type of phosphor used on the screen. The green hue may cause crewmembers to experience a pink, brown, or purple afterimage when they remove NVG. This is called monochromatic adaptation and is a normal physiological phenomenon. The length of time the afterimage remains varies with each individual.

300
Q

The OSAP procedure is used for what purpose?

A

A point where the optical axes of the ANVIS is aligned with your visual line-of-sight and where the ANVIS’ eyepieces are at the maximum distance from your eyes that still allow you to see the intensified image full field-of-view.

*** To precisely align each monocular to the individual eye to obtain the optimal sight picture.

301
Q

A

overcast conditions

flares or illumination rounds

305
Q

The function of Automatic Brightness Control (ABC) is?

A

automatically adjusts MCP voltage to maintain image brightness at preset levels by controlling the number of electrons that exit the MCP.

***Automatically reduces the voltage to the Micro-channel Plate to keep the image intensifiers brightness within a set limit. It creates a stable
image for the Aviator and prevents the output from becoming bright enough to impact the Aviators dark adaptation.

306
Q

This function reduces the voltage to the photocathode when the ANVIS is exposed to bright light sources. This function also protects the image intensifier from damage and enhances its life; however, it also has the effect of lowering resolution.

A

bright source protection (BSP)

307
Q

What factors increase the stress of aircrews during terrain flight, and how can these be minimized?

A

Knowledge that the darkness makes it difficult to see obstructions along the flight path causes stress.

Added stress increases fatigue which
impairs judgment, slows reaction time, and degrades flight proficiency.

Increased experience and proper personal preparation enables
aircrews to cope with the stress of night terrain flight.

Proper preparation includes eating a good balanced diet, staying in good physical
condition and getting enough sleep.

308
Q

This is a condition that causes the lenses to harden, is part of the normal aging process.
