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

, (A&P Airframe Oral Exam (Jeppesen) – Latest version with clear Questions, Answers, and Rationales2026)
Question: What is a spring tab?
Answer: A tab that assists control movement at high speeds.
Rationale: It activates when control forces become too great for manual input.
8. Balance Trim Tab
Question: What is a balance trim tab?
Answer: A tab connected to the structure that helps move a control surface.
Rationale: It offsets aerodynamic loads, making controls easier to move.
9. High-Lift Devices
Question: What are the four most common types?
Answer: Flaps, slats, slots, and leading/trailing edge devices.
Rationale: These increase lift at low speeds for safer takeoff and landing.
10. Control Surface Measurement Tools
Question: What tools check control surface travel?
Answer: Universal propeller protractor or control surface protractor.
Rationale: Ensures surfaces move within manufacturer limits.
11. Flight Control Actuation
Question: Name three mechanical actuation methods.
Answer: Cables, push-pull rods, and torque tubes.
Rationale: These transmit pilot input to control surfaces.
12. Fairlead
Question: What is a fairlead?
Answer: A guide that prevents cable wear on structure.
Rationale: Reduces friction and prolongs cable life.
13. Cable Wear Locations
Question: Where do cables most likely wear or break?
Answer: Over pulleys or through fairleads.
Rationale: These are high-friction and stress points.
14. Cable Rigging Requirements
Question: What info is needed before using a rigging chart?
Answer: Ambient temperature and cable size.
Rationale: Temperature affects cable tension.
15. Cable Tension Regulator

, (A&P Airframe Oral Exam (Jeppesen) – Latest version with clear Questions, Answers, and Rationales2026)
Question: What is its function?
Answer: Maintains proper tension despite expansion/contraction.
Rationale: Ensures consistent control performance.
16. Collective Pitch Control
Question: What does it do?
Answer: Changes pitch of all rotor blades equally.
Rationale: Controls total lift in helicopters.
17. Cyclic Pitch Control
Question: What does it do?
Answer: Changes blade pitch during rotation to tilt rotor disc.
Rationale: Controls helicopter direction.
18. Anti-Torque System
Question: What compensates for main rotor torque?
Answer: Tail rotor.
Rationale: Prevents fuselage from spinning.
19. Tail Rotor Control
Question: How is thrust controlled?
Answer: Foot pedals.
Rationale: Adjusts yaw.
20. Control Surface Locking
Question: Why lock controls when parked?
Answer: To prevent wind damage.
Rationale: Wind can move surfaces violently and cause structural damage.
21. Aluminum Damage
Question: What is the main weather-related damage?
Answer: Corrosion.
Rationale: Moisture and oxygen degrade aluminum over time.
22. Sheet Metal Forming
Question: Name forming methods.
Answer: Bending, stretching, shrinking, crimping, bumping.
Rationale: These shape metal for structural use.
23. Rivet Dimensions
