1. What is the primary purpose of an altimeter in an aircraft?
A. Measures airspeed
B. Measures altitude above sea level
C. Measures engine temperature
D. Measures fuel quantity
Answer: B
Rationale: An altimeter measures atmospheric pressure to determine
the aircraft’s altitude above mean sea level.
2. Which force opposes lift during flight?
A. Thrust
B. Weight
C. Drag
D. Gravity
Answer: C
Rationale: Drag is the aerodynamic force that resists an aircraft’s
motion through the air.
3. The four forces acting on an aircraft are lift, weight, thrust, and:
,A. Pressure
B. Drag
C. Speed
D. Torque
Answer: B
Rationale: The four basic aerodynamic forces include lift, weight,
thrust, and drag.
4. What does a compass primarily indicate?
A. Speed
B. Direction relative to magnetic north
C. Altitude
D. Fuel level
Answer: B
Rationale: A magnetic compass shows aircraft heading relative to
magnetic north.
5. Which gas is most abundant in Earth’s atmosphere?
A. Oxygen
B. Carbon dioxide
C. Nitrogen
D. Hydrogen
Answer: C
Rationale: Nitrogen makes up about 78% of Earth’s atmosphere.
,6. What is lift primarily generated by?
A. Gravity
B. Aircraft weight
C. Airflow over wings
D. Engine thrust only
Answer: C
Rationale: Lift is produced by the pressure difference created as air
flows over the wing.
7. What does “airspeed” measure?
A. Ground distance covered
B. Speed relative to air mass
C. Fuel burn rate
D. Engine RPM
Answer: B
Rationale: Airspeed is the speed of the aircraft relative to the
surrounding air.
8. Which instrument indicates vertical speed?
A. Altimeter
B. VSI
C. Airspeed indicator
D. Compass
Answer: B
Rationale: The Vertical Speed Indicator (VSI) shows rate of climb or
descent.
, 9. What causes aircraft weight?
A. Engine thrust
B. Gravity acting on mass
C. Air resistance
D. Lift force
Answer: B
Rationale: Weight is the force of gravity acting on the aircraft’s mass.
10. What is the standard unit of atmospheric pressure used in
aviation?
A. Celsius
B. Newton
C. Hectopascal
D. Watt
Answer: C
Rationale: Hectopascal (hPa) is the standard unit used for pressure in
aviation.
11. What is the function of flaps?
A. Increase cruise speed
B. Reduce engine power
C. Increase lift at low speeds
D. Steer the aircraft
Answer: C
