1. What is the primary purpose of an aircraft pre-flight inspection?
A. To increase engine power
B. To ensure passenger comfort
C. To confirm aircraft is safe for flight
D. To reduce fuel consumption
Correct Answer: C. To confirm aircraft is safe for flight
Rationale: A pre-flight inspection is conducted to identify any visible
defects, ensure systems are functional, and confirm that the aircraft is
airworthy before departure.
2. Which force opposes thrust during flight?
A. Lift
B. Weight
C. Drag
D. Gravity
Correct Answer: C. Drag
Rationale: Drag is the aerodynamic force that resists an aircraft’s
motion through the air, acting opposite to thrust.
,3. The four main forces acting on an aircraft in flight are?
A. Lift, weight, thrust, drag
B. Power, speed, lift, fuel
C. Thrust, gravity, speed, pressure
D. Lift, inertia, drag, momentum
Correct Answer: A. Lift, weight, thrust, drag
Rationale: Aircraft flight is governed by four fundamental forces that
must be balanced for controlled flight.
4. What does lift primarily counteract?
A. Thrust
B. Drag
C. Weight
D. Gravity only
Correct Answer: C. Weight
Rationale: Lift is the upward aerodynamic force that opposes the
downward force of gravity (weight).
5. Which instrument measures airspeed?
A. Altimeter
B. Airspeed indicator
C. Compass
D. Turn coordinator
,Correct Answer: B. Airspeed indicator
Rationale: The airspeed indicator measures the aircraft’s speed
relative to the surrounding air.
6. What does an altimeter measure?
A. Engine pressure
B. Air temperature
C. Altitude above sea level
D. Fuel quantity
Correct Answer: C. Altitude above sea level
Rationale: An altimeter measures the aircraft’s vertical position
relative to mean sea level using atmospheric pressure.
7. Which gas is most commonly used in aircraft tires?
A. Oxygen
B. Nitrogen
C. Hydrogen
D. Carbon dioxide
Correct Answer: B. Nitrogen
Rationale: Nitrogen is used because it is dry, stable, and less affected
by temperature changes compared to air.
8. What is the primary function of flaps?
A. Increase engine power
B. Increase lift at low speeds
, C. Reduce aircraft weight
D. Improve fuel quality
Correct Answer: B. Increase lift at low speeds
Rationale: Flaps increase the wing’s camber and surface area,
allowing more lift at slower speeds during takeoff and landing.
9. Which part of the aircraft provides most of the lift?
A. Fuselage
B. Engine
C. Wings
D. Landing gear
Correct Answer: C. Wings
Rationale: Wings are designed with an airfoil shape that generates lift
as air flows over them.
10. What is thrust primarily produced by?
A. Wings
B. Engine
C. Rudder
D. Elevator
Correct Answer: B. Engine
Rationale: The engine generates thrust to move the aircraft forward.
11. What does the rudder control?
A. Pitch
