1. What is the primary purpose of an aircraft’s wing flaps?
A. Reduce drag during cruise
B. Increase lift during takeoff and landing
C. Improve engine performance
D. Decrease stall speed in climb
Rationale:
Flaps increase the camber and surface area of the wing, generating more
lift at lower speeds, which is essential for takeoff and landing.
,2. What type of metal is most commonly used in aircraft structures?
A. Steel
B. Aluminum alloys
C. Copper
D. Magnesium
Rationale:
Aluminum alloys offer a high strength-to-weight ratio and corrosion
resistance, making them ideal for aircraft structures.
3. What is the function of a torque tube in an aircraft control system?
A. Increase control force
B. Transmit rotary motion
C. Reduce drag
D. Act as a spring
Rationale:
Torque tubes transmit rotary motion from the cockpit controls to control
surfaces while maintaining structural rigidity.
4. Which inspection is required at 100-hour intervals on an aircraft used
for hire?
,A. Annual inspection only
B. Preflight inspection
C. 100-hour inspection
D. Progressive inspection
Rationale:
FAA regulations require aircraft used for hire to undergo a 100-hour
inspection to ensure continued airworthiness.
5. What is the primary purpose of wing spars?
A. Carry fuel
B. Provide structural support
C. Control lift distribution
D. Reduce drag
Rationale:
Wing spars are the main structural members of a wing, carrying bending
and torsional loads.
6. Which of the following is considered an NDI (Non-Destructive
Inspection) method?
A. Sanding
B. Ultrasonic inspection
, C. Welding
D. Cutting
Rationale:
Ultrasonic inspection allows detection of internal flaws without damaging
the part, a common NDI technique.
7. What is the function of ailerons on an aircraft?
A. Control pitch
B. Control roll
C. Control yaw
D. Increase lift
Rationale:
Ailerons are mounted on the trailing edges of wings and move in opposite
directions to roll the aircraft.
8. What does the term “tangency” refer to in sheet metal work?
A. Welding angle
B. Rivet spacing
C. The point where two surfaces meet smoothly
D. Sheet metal thickness
