2. Which of the following is considered a primary flight control?
A. Slats.
B. Elevators.
C. Dorsal fin. ** Answ** B. Elevator
3. Which of the following are considered primary flight controls?
A. Tabs.
B. Flaps.
C. Outboard ailerons. ** Answ** C. Outboard ailerons.
4. When are inboard ailerons normally used?
A. Low-speed flight only.
B. High-speed flight only.
C. Low-speed and high-speed flight. ** Answ** C. Low-speed and high speed flight.
5. When are outboard ailerons normally used?
,A. Low-speed flight only.
B. High-speed flight only.
C. Low-speed and high-speed flight. ** Answ** A. Low-speed flight only.
6. Why do some airplanes equipped with inboard/outboard ailerons use the outboards for slow
flight only?
A. Increased surface area provides greater controllability with flap extension.
B. Aerodynamic loads on the outboard ailerons tend to twist the wingtips at high speeds.
C. Locking out the outboard ailerons in high-speed flight provides variable flight control feel.
** Answ** B. Aerodynamic loads on the outboard ailerons tend to twist the wingtips at high
speeds.
7. What is the purpose of a control tab?
A. Move the flight controls in the event of manual reversion.
B. Reduce control forces by deflecting in the proper direction to move a primary flight control.
C. Prevent a control surface from moving to a full-deflection position due to aerodynamic forces.
** Answ** A. Move the flight controls in the event of manual reversion.
8. What is the purpose of an elevator trim tab?
A. Provide horizontal balance as airspeed is increased to allow hands-off flight.
B. Adjust the speed tail load for different airspeeds in flight allowing neutral control forces.
C. Modify the downward tail load for various airspeeds in flight eliminating flight-control
pressures. ** Answ** C. Modify the downward tail load for various airspeeds in flight
eliminating flight-control pressures.
9. Which direction from the primary control surface does an elevator adjustable trim tab move
when the control surface is moved?
,A. Same direction.
B. Opposite direction.
C. Remains fixed for all positions. ** Answ** C. Remains fixed for all positions.
10. What is the purpose of a servo tab?
A. Move the flight controls in the event of manual reversion.
B. Reduce control forces by deflecting in the proper direction to move a primary flight control.
C. Prevent a control surface from moving to a full-deflection position due to aerodynamic forces.
** Answ** B. Reduce control forces by deflecting in the proper direction to move a primary
flight control.
11. Which direction from the primary control surface does a servo tab move?
A. Same direction.
B. Opposite direction.
C. Remains fixed for all positions. ** Answ** B. Opposite direction.
12. What is the purpose of an anti-servo tab?
A. Move the flight controls in the event of manual reversion.
B. Reduce control forces by deflecting in the proper direction to move a primary flight control.
C. Prevent a control surface from moving to a full-deflection position due to aerodynamic forces.
** Answ** C. Prevent a control surface from moving to a full-deflection position due to
aerodynamic forces.
13. Which direction from the primary control surface does an anti-servo tab move?
A. Same direction.
B. Opposite direction.
, C. Remains fixed for all positions. ** Answ** A. Same direction
14. The primary purpose of high-lift devices is to increase the
A. L/DMAX.
B. lift at low speeds.
C. drag and reduce airspeed. ** Answ** B. lift at low speeds.
15. Which is a purpose of leading-edge flaps?
A. Increase the camber of the wing.
B. Reduce lift without increasing airspeed.
C. Direct airflow over the top of the wing at high angles of attack. ** Answ** A. Increase
the camber of the wing.
16. What is the primary function of the leading edge flaps in landing configuration during the
flare before touchdown?
A. Prevent flow separation.
B. Decrease rate of sink.
C. Increase profile drag. ** Answ** A. Prevent flow separation.
17. What effect does the leading edge slot in the wing have on performance?
A. Decreases profile drag.
B. Changes the stalling angle of attack to a higher angle.
C. Decelerates the upper surface boundary layer air. ** Answ** B. Changes the stalling
angle of attack to a higher angle.
18. Which is a purpose of leading-edge slats on high-performance wings?
