A. Measure airspeed
B. Measure altitude above sea level
C. Measure fuel quantity
D. Measure engine power
Correct Answer: B
Rationale: An altimeter measures the aircraft’s altitude above mean
sea level by detecting changes in atmospheric pressure.
2. What does ATC stand for in aviation?
A. Air Traffic Control
B. Aircraft Terminal Communication
C. Air Travel Coordination
D. Automatic Transmission Control
Correct Answer: A
Rationale: ATC refers to Air Traffic Control, the service responsible for
managing aircraft movement on the ground and in the air.
,3. Which instrument indicates aircraft speed relative to the air?
A. Altimeter
B. Airspeed indicator
C. Turn coordinator
D. Compass
Correct Answer: B
Rationale: The airspeed indicator measures the speed of the aircraft
through the air, not over the ground.
4. What is the standard unit of altitude used in aviation?
A. Meters
B. Kilometers
