1. What is the primary purpose of lift in aviation?
A. To slow the aircraft
B. To oppose gravity
C. To increase fuel efficiency
D. To control engine power
Correct Answer: B
RATIONALE:
Lift is the aerodynamic force that directly opposes the weight (gravity)
of the aircraft, allowing it to become and remain airborne. Without
lift, an aircraft cannot sustain flight.
2. Which force acts downward on an aircraft?
A. Thrust
B. Drag
C. Weight
D. Lift
Correct Answer: C
,RATIONALE:
Weight is the force caused by gravity pulling the aircraft toward Earth.
It always acts vertically downward regardless of aircraft attitude.
3. What is the function of the aircraft ailerons?
A. Control yaw
B. Control pitch
C. Control roll
D. Control thrust
Correct Answer: C
RATIONALE:
Ailerons control roll by increasing lift on one wing and decreasing lift
on the other, causing the aircraft to bank left or right.
4. The rudder controls movement around which axis?
A. Longitudinal axis
B. Lateral axis
C. Vertical axis
D. Horizontal axis
Correct Answer: C
RATIONALE:
The rudder controls yaw movement around the vertical axis, allowing
the nose of the aircraft to move left or right.
, 5. What does the elevator primarily control?
A. Roll
B. Pitch
C. Yaw
D. Thrust
Correct Answer: B
RATIONALE:
The elevator controls pitch by moving the nose of the aircraft up or
down around the lateral axis.
6. Which layer of the atmosphere contains most weather
phenomena?
A. Stratosphere
B. Troposphere
C. Mesosphere
D. Thermosphere
Correct Answer: B
RATIONALE:
The troposphere is the lowest atmospheric layer and contains clouds,
wind, precipitation, and most weather systems.
7. What is the standard atmospheric pressure at sea level?
A. 1013.25 hPa
B. 500 hPa
, C. 760 hPa
D. 29.92 hPa only in meters
Correct Answer: A
RATIONALE:
Standard atmospheric pressure is 1013.25 hPa (hectopascals),
equivalent to 29.92 inHg.
8. What is the main purpose of an altimeter?
A. Measures airspeed
B. Measures altitude
C. Measures fuel
D. Measures heading
Correct Answer: B
RATIONALE:
An altimeter measures aircraft altitude above mean sea level using
atmospheric pressure.
9. What causes lift in an aircraft wing?
A. Gravity only
B. Pressure difference over and under the wing
C. Engine thrust only
D. Fuel combustion
Correct Answer: B
