1. What is the primary purpose of wing-mounted vortex generators?
A) Increase the onset of drag divergence and aid in aileron effectiveness at low
speed.
B) Break the airflow over the wing so the stall will progress from the root out to
the tip of the wing.
C) Delays the onset of drag divergence at high speeds and aids in maintaining
aileron effectiveness at high speeds.
Answer: C
Rationale: Vortex generators are designed to energize the boundary layer,
delaying flow separation and maintaining control effectiveness at high
speeds.
2. During a go-around, the aircraft experiences a sudden roll to the left. What
is the most likely cause?
A) Aileron control reversal due to a malfunction.
B) A sudden loss of engine power on the right side.
C) A sudden increase in engine power on the left side.
Answer: C
,Rationale: A sudden increase in engine power on the left side can cause a
yawing moment to the left, which may induce a roll if not counteracted.
3. What is the primary function of flight spoilers?
A) Increase the camber of the wing.
B) Reduce lift without decreasing airspeed.
C) Direct airflow over the top of the wing at high angles of attack.
Answer: B
Rationale: Flight spoilers are used to reduce lift and increase drag, aiding in
descent and roll control.
4. Which of the following is considered a primary flight control?
A) Elevator.
B) Dorsal fin.
C) Slats.
Answer: A
Rationale: Primary flight controls include ailerons, elevators, and rudders,
which directly control the aircraft's attitude.
5. When are inboard ailerons normally used?
A) High-speed flight only.
B) Low-speed flight only.
C) Low-speed and high-speed flight.
Answer: A
Rationale: Inboard ailerons are typically used at high speeds to reduce control
forces and improve stability.
6. What is the purpose of wing-mounted vortex generators?
A) Increase the onset of drag divergence and aid in aileron effectiveness at low
speed.
, B) Break the airflow over the wing so the stall will progress from the root out to
