Hillclimber Study Guide Flashcards
You are flying over an open body of water which is devoid of any visual references when suddenly you are unable to visually judge the aircraft’s true altitude. This causes you to inadvertently begin an uncommanded descent which results in a dangerously low altitude.
This is an example of what type of visual illusion?
Height-depth perception
Operational Defects relate to the reliability of the image intensifier and are an indication of instability in the AN/AVS-6.
What are the operational defects?
Shading, Edge Glow, Flashing & Flickering, Intermittent Operation, and Emission Points
Aviators must be familiar with high bank angle turn characteristics, anticipate cyclic input results, and apply appropriate control inputs to conduct combat maneuvers successfully.
When flying heavy aircraft in a high hot environment, sufficient time and altitude may not be available to arrest the resultant descent.
A bank angle of 45 degrees requires an increase in torque of what percent to maintain airspeed and altitude?
41.4 %
(MOUNTAINOUS OPERATIONS): When flying in a valley, what location requires less power and provides the aircraft a safer flight path?
On the side farthest away from the predominant wind direction, where there is smoother up-flowing air.
Life rafts sufficient for all persons on board (see TM 1-1500-204-23-1) are required on CH-47 aircraft during flights ___________.
Made more than 30 minutes flying time from nearest shoreline.
100 nautical miles from the nearest shoreline.
Flying in areas where turbulence is forecast should be avoided. However, if forced to enter an area with moderate turbulence, what airspeed should you use?
Vne minus 10 KCAS or to maximum range, whichever is slower.
_________ speed is the airspeed range providing the best power margin for maneuvering flight.
Bucket Speed
To avoid incursions in the yellow and/or zone of the Cruise Guide Indicator, perform one of more of the following:
Reduce Airspeed
Reduce severity of the maneuver
Lower Thrust
When the caution, “DUAL HOOK FAULT” appears, you should:
Manually release the load
__________ or anemic, hypoxia is caused by a reduction in blood’s 02-carrying capacity.
Anemia and blood loss are the most common causes of this type of hypoxia.
Hypemic
Job stress, illness, and family issues (things that happen externally to us that can impact us internally), are all examples of what kind of stressors?
Cognitive (mental)
A false sensation of angular displacement about the roll axis (sensation that aircraft is one-wing low) is what illusion?
Leans
When operating in noise sensitive areas, unless required by the mission, all Army aircraft will maintain a minimum ______ of feet above the surface of the following: national parks, monuments, recreation areas and scenic river ways ad-ministered by the National Parks Service; National Wildlife Refuges, Big Game Refuges, or Wildlife Ranges operated by the U.S. Fish and Wildlife Service; and wilderness and primitive areas administered by the U.S. Forest Service.
2000
Practice hooded approaches may be made to the decision altitude or minimum descent altitude (MDA) when the aircraft has dual controls and a pilot without vision restriction is at one set of controls. In all other cases, hooded approaches may not be made lower than how many feet AGL?
500
Oxygen will be used by aircraft crews and occupants for flights as follows:
On flights above 14,000 feet pressure altitude for any period of time.
If no IFR Departure Procedure is published, climb runway heading to _________ above the departure end of runway elevation; turn in the shortest direction of the first filed point.
This procedure keeps the aircraft clear of terrain and obstructions as long as the climb is at ______.
400’ AGL, 200 FPNM
This altitude provides obstruction clearance within each bounded latitude/longitude quadrant plus 4 NM as shown on FAA IFR charts. It is intended primarily as a pilot tool for emergencies and situational awareness. It does not provide an acceptable obstruction clearance for the purposes of off-route, random RNAV direct flight in either controlled or uncontrolled airspace.
Off Route Obstruction Clearance Altitude (OROCA)
The Minimum Sector Altitude on the VOR or TACAN-B instrument approach procedure:
2,000FT obstacle clearance 25NM around HNL VORTAC
Referring to the VOR or TACAN-B instrument approach procedure, what is the lowest predominant weather you need to file to at Wheeler AFF (Category A) without the requirement of an alternate?
1000ft ceiling - 2 mile visibility
You are transitioning VFR above Molokai (PHMK) airspace at 4,000’ MSL, what are your visibility and cloud clearance requirements?
3 SM / 500ft below, 1000ft above, 2000ft horizontal
