Accurate Solutions
1. The collective pitch control
2. The cyclic pitch control
3. The ANTItorque pedals - ANS-What are the three major controls in a helicopter?
100% of Maximum. Normal helicopter landings usually require high power settings, with
terminations to a hover requiring the highest power setting. - ANS-What power setting
should be used during terminations to a hover?
45 Knots at 25-40 feet. Also, be sure this is done into the wind - ANS-When training for
rapid deceleration, in most helicopters the entry speed should be approximately how
many knots and at what altitude?
A 2G turn is 60 degrees - ANS-How many degrees is a 2G turn?
A forward center of gravity is not obvious when hovering into a strong headwind. A
forward center of gravity is easily recognized when coming to a hover following a
vertical takeoff, but not as obvious when hovering into a strong headwind, since less
rearward cyclic displacement is required than when hovering with no wind. - ANS-When
is a forward center of gravity not obvious?
A governor - ANS-What engine component is common to all turbine helicopters and
some piston helicopters?
A high reconnaissance is flown at 300 to 500 feet - ANS-What altitude is a high
reconnaissance flown at?
A hover taxi is used when operating below 25 feet above ground level (AGL) - ANS-At
what altitude is a hover taxi used?
An approach angle of 13-15* is considered a steep approach - ANS-What approach
angle is considered a steep approach?
Bernoulli's principle describes the relationship between internal fluid pressure and fluid
velocity. It is a statement of the law of conservation of energy and helps to explain why
an airfoil develops an aerodynamic force - ANS-What does Bernoulli's principle
describe?
, Cyclic feather changes angle of incidence (AOI) differentially around teh rotor system,
this creates a differential lift int he rotor system by changing the angle of attack (AOA)
differentially across the rotor system. Aviators use cyclic feathering to control the
attitude of the rotor system. - ANS-What does Cyclic Feathering do?
During aft cyclic, torque decreases and rotor speed increases - ANS-What happens to
torque and rotor RPM during aft cyclic?
During forward cyclic, torque increases and rotor speed decreases - ANS-What
happens to torque and rotor RPM during forward cyclic?
During left turns, torque increases in most helicopters - ANS-During left turns, what
happens to Torque in most helicopters?
During right turns, torque decreases in most helicopters - ANS-During right turns, what
happens to Torque in most helicopters?
Each gallon of JP-4 weighs 6.5lbs - ANS-How much does each gallon of JP-4 weigh?
Each gallon of reciprocating engine oil weighs 7.5 Pounds - ANS-How much does each
gallon of reciprocating engine oil weigh?
Engine power must be increased 100% in a 2G turn - ANS-How much must engine
power be increased to maintain airspeed in a 2G turn?
Load factor is the effective weight. When a helicopter is maneuvering, centrifugal force
adds extra weight to the fuselage. This extra weight, when added to the weight of the
helicopter, crew, passengers, and cargo, becomes the effective weight of the helicopter,
or load factor. - ANS-What is the load factor?
Loss of effective ETL occurs at approximately 25 knots. The antitorque pedals should
be adjusted below 100 feet AGL to alignthe helicopter with the touchdown point - ANS-
During a steep approach, the helicopter should be kept in trim just prior to loss of
effective translational lift, which is occurs at what speed? Also, at how many feet should
the antitorque pedals be adjusted to align the helicopter with the touchdown point?
The AH-64 Apache features four hardpoints mounted on stub-wing pylons, and usually
carries a combination of AGM-114 Hellfire missiles and Hydra 70 rocket pods - ANS-
What is the Army's primary attack helicopter and what are it's armaments?
The air frame passing through the air - ANS-Parasite Drag is caused by what?
The anti-torque pedals control what direction the helicopters nose is pointing during a
however, and controls trim during regular flight - ANS-What controls the direction the
helicopters nose is pointing during a hover, and adjusts trim in forward flight?
