clear Questions,
Answers, and
Rationales
, 1. Vortex Generators
Question: What is the function of a vortex generator?
Answer: It delays or prevents separation of the boundary layer.
Rationale: By energizing airflow over the wing, vortex generators maintain smooth airflow at
higher angles of attack, improving lift and preventing stalls.
2. Axes of an Airplane
Question: What are the three axes of an airplane?
Answer: Longitudinal, lateral, and vertical.
Rationale: These axes define aircraft movement: roll (longitudinal), pitch (lateral), and yaw
(vertical).
3. Primary Flight Controls
Question: What are the three primary flight controls?
Answer: Ailerons, elevators, and rudder.
Rationale: These directly control aircraft attitude and direction along the three axes.
4. Secondary Flight Controls
Question: Name several secondary flight controls and their purpose.
Answer: Trim tabs (balance, servo, anti-servo, spring tabs) help move controls and allow
hands-off flight.
Rationale: They reduce pilot workload and improve control efficiency.
5. Auxiliary Flight Controls
Question: What are auxiliary flight controls?
Answer: High-lift devices like flaps, slats, slots, and speed brakes.
Rationale: These improve performance during low-speed operations such as takeoff and
landing.
6. Servo Trim Tab
Question: What is a servo trim tab?
Answer: A tab that moves with the control surface to assist its movement.
Rationale: It reduces pilot effort by using aerodynamic forces.
7. Spring Tab
