greater than it - ANS-When generating lift, what should the pressure below the airfoil be
in relation to the pressure above the airfoil?
2 - ANS-what is the load factor of a 2000 pound helicopter that is currently experiencing
an effective load of 4000 pounds?
parasitic drag and profile drag - ANS-What type/types of drag increases as the speed
increases?
RPM - ANS-which of the following decreases upon an increase to the collective pitch
controller?
-adjusts the throttle as needed
-uses an electronic sensor
-regulates power to maintain RPM
-requires almost no manual control - ANS-governor:
left; left - ANS-if the cyclic pitch control is pushed to the left, which way will the rotor disk
tip and which way will the helicopter move?
left and right - ANS-which directions are the anti-torque pedals designed to move the
nose?
pilot - ANS-which of the following is not included in a helicopter's base empty weight?
a. pilot
b. engine
c. optional equipment
d. transmission oil
e. rotors
decreased performance and structural damage - ANS-what are the dangers of
overloading a helicopter?
front loaded center of gravity - ANS-if the helicopter is nose down while attempting to
hover, and there are no winds, then it most likely has...
slowly adjust the anti torque pedals - ANS-when performing a vertical takeoff to a hover,
what should be done if the heading begins to change?
, c. heading - ANS-which of the following would not need to be maintained while
performing a hovering turn?
a. altitude
b. rpm
c. heading
d. position
e. center of gravity
additional pressure needed on the anti torque pedals to deal with the weathervane -
ANS-what is a complication unique to sideward hovering flight as opposed to forward
and rearward flight?
-flying in shaded area of height-velocity diagram
-flying over other aircraft, vehicles, and personnel
-flying in crosswind conditions - ANS-what should be avoided when performing an air
taxi?
c. rpm - ANS-which of the following does not need to be checked before beginning a
normal takeoff from hover?
a. power
b. balance
c. rpm
d. flight controls
e. fuel levels
cyclic pitch control - ANS-in straight and level flight, which control is primary used to
increase airspeed?
imbalanced center of gravity - ANS-a helicopter is attempting to take off when she
notices that the helicopter's nose tilts down after leading the ground. what is most likely
the problem?
-using the 10% of the rate rule--c. 240 feet - ANS-a helicopter begins a descent at 300
feet above the ground, with the intent to lower to 200 feet above the ground. the pilot
begins the descent at a steady rate of 400 FMP. at what altitude should he begin
leveling out the helicopter?
a. 200 feet
b. 220 feet
c. 240 feet
d. 260 feet
e. 300 feet

in the maximum internal weight?
a. pilot
