TD38 & 41 Flashcards
In reference to TC 3-04.4, what is the caution associated with wire hazards? What are two specific cues for locating wires?
Wires are nearly impossible to see with NVDs. They are also difficult to see during certain times of day, for example when flying into a setting sun. Wires and poles can become coated in dust and snow making them even harder 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.
Cut through vegetation and supporting poles.
Where are the two locations that the Storm Scope information can be displayed?
On the Nav Display or the PFD ARC mode.
What is the NOTE associated with the Storm Scope as written in the current AWR 1726? What is the CAUTION associated with Storm Scope WX-500 operation, and how long is storm activity stored in the memory and displayed?
Note: The WX 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 NM.
Caution: Clusters of two or more discharge points in the strike display mode indicate thunderstorm activity when they reappear even after clearing the screen. In the cell mode, even a single discharge point may represent thunderstorm activity and should be avoided.
How does the Mechanical Mixing Unit compensate for torque effect and the vertical thrust component of the canted tail rotor?
Collective to yaw compensates for torque effect: The pitch of the tail rotor will increase as collective is increased and vice versa.
Yaw to pitch compesates for the vertical thrust of the tail rotor, as the pitch of the tail rotor increases, the main rotor will tilt aft.
In reference to TC 3-04.4, what are three specific hazards to terrain flight safety? Give one example for each.
Physical hazards: Natural trees, birds ambient light. Manmade: buildings, bridges, towers, other aircraft and wires.
Weather hazards: Restricted visibility or wind conditions.
Human factors: Fatugue, lack of ability to detect obstacles.
How do you create a storepoint and how many storepoints can be created?
double tap the FIX key, or you can press mark on the flyover store screen while flying over a point or by selecting it on the tac map
Why does the yellow EIC miscompare annunciation appear and what is the miscompare threshold for TGT?
If there’s a significant different between what the DCUs are detecting it will display a miscompare. Miscompare threshhold for TGT is 7.3 degrees C.
In reference to UH-60 ATM, what is the WARNING associated with Level
Acceleration Takeoff?
Warning: If the takeoff is aborted, it may be impossible to stop the aircraft before clearing the barriers . Some situations requiring this maneuever will usualy result in very marginal single engine characteristics. This increased risk factor will be addressed during the mission risk assessment process.
What does the Go Around (Go ARND) Mode provide, and how is it engaged? Can the pilot change FPM ROC and airspeed reference?
The go around mode provides pitch, roll, collective cues and FPS commands to establish a wings level 750 fpm rate of climb while maintaining 70 kts. It can be engaged by pressing the go around button on the flight director, or using the go around button on the cyclic.
The pilot cannot change the 750 fpm and 70 kt airspeed references however, the pilot can at any time engage IAS or VS modes to adjust the airspeed and rate of climb.
When is the LOC legend displayed on the FD/DCP? When will BC be displayed on the FD/DCP?
The LOC legend is displayed on the FD 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 degrees
BC is displayed when a localizer source is selected, and the difference between the selected course and the actual heading is less than 105 degrees.
What does the ILS DECL mode provide?
The ILS DECL provides a means to automatically decelerate the helicopter from its present airspeed to 70 kts prior to the 200 ft AGL point on the glide slope. GS must already be engaged, and the present altitude must be such that the DECL mode can achieve 70 kts prior to 200 ft with a 0.5 kt per second rate.
When can the VOR navigation mode be engaged?
The VOR nav mode can only be engaged at airspeeds of 50 kts or above. VOR can only be engaged when a valid VOR freq is tuned and the FCC is receiving a VOR signal.
When will the VOR mode switch to station passage mode? What happens during this mode?
The VOR mode will switch to station passage mode when the FCC determines that the helicopter is over the VOR station. The CAP annunciation on the FD will change to SP to show the change in mode. The helicopter will stop trying to track the VOR radial and will maintain the heading. During station passage, if the selected course is changed, the helicopter will turn to the new selected course. CAP mode will come back when the FCC determines the VOR has stabilized enough, or approximately 3 miles from the VOR station.
While in the SP mode, when will the FD/DCP indicate VOR CAP again?
CAP mode will come back when the FCC determines the VOR has stabilized enough, or approximately 3 miles from the VOR station, whichever happens first.
What is the difference between a sign of hypoxia and a symptom of hypoxia?
Signs are effects on the body that 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.
What are the signs and symptoms of Hypoxia?
Signs: Hyperventilation, Cyanosis (lips turn blue), mental confusion, poor judgement, lack of muscle coordination.
Symptoms: Increased breathing rate, apprehension, fatigue, headache, dizziness, hot and cold flashes, denial.
What does the T in the triangle indicate in the margin data?
That airport has takeoff minimums or obstacle departure procedures.
The MSA for MAI VORTAC is 25 NM. What does this provide? Explain Minimum Sector and Emergency Safe Altitudes.
MINIMUM SAFE ALTITUDE –
Altitudes depicted on approach charts which provide at least 1000 ft 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.
MINIMUM SECTOR ALTITUDES –
Altitudes depicted on approach charts which provide at least 1000 ft of obstacle clearance within a 25 mile radius of the navigation facility on which the procedure is predicated. These are for emergency use only and do not necessarily assure acceptable navigational signal coverage.
EMERGENCY SAFE ALTITUDES –
Altitudes depicted on approach charts which provide at least 1000 ft of obstacle clearance in non-mountainous areas and 2000 ft of obstacle clearance in mountainous areas within a 100 NM radius of the nav facility upon which the procedure is predicated. Normally only used in military procedures.
