1. During a standard atmosphere at sea level, the standard pressure
is:
A. 30.12 inHg
B. 28.92 inHg
C. 29.92 inHg
D. 31.00 inHg
Answer: C. 29.92 inHg
Explanation: Standard atmospheric pressure at sea level is 29.92 inches
of mercury, which serves as the reference for pressure altitude
calculations.
2. Which flight control primarily controls the airplane's roll?
A. Rudder
B. Elevator
,C. Ailerons
D. Trim tab
Answer: C. Ailerons
Explanation: Ailerons move in opposite directions to produce roll about
the longitudinal axis.
3. What is the primary purpose of the elevator?
A. Control yaw
B. Control pitch
C. Control roll
D. Increase thrust
Answer: B. Control pitch
Explanation: The elevator changes the airplane's pitch attitude around
the lateral axis.
4. Which instrument is powered only by the pitot system?
A. Altimeter
B. Vertical Speed Indicator
C. Airspeed Indicator
D. Heading Indicator
Answer: C. Airspeed Indicator
Explanation: The airspeed indicator measures dynamic pressure from
the pitot tube compared with static pressure.
, 5. If the pitot tube becomes blocked while the drain hole remains
open, the airspeed indicator will:
A. Indicate zero
B. Indicate altitude
C. Read normally
D. Increase continuously
Answer: A. Indicate zero
Explanation: With the pitot tube blocked and drain open, pressure
escapes and the indicator drops toward zero.
6. Which force opposes thrust in flight?
A. Lift
B. Drag
C. Weight
D. Gravity
Answer: B. Drag
Explanation: Drag is the aerodynamic force resisting the airplane's
forward motion.
7. Increasing the angle of attack beyond the critical angle will result
in:
A. Increased lift indefinitely
B. A stall
C. Increased thrust
, D. Lower drag
Answer: B. A stall
Explanation: Exceeding the critical angle of attack causes airflow
separation and loss of lift.
8. Which weather condition is most favorable for carburetor icing?
A. Cold, dry air
B. Warm, dry air
C. Moderate temperatures with high humidity
D. Very hot desert air
Answer: C. Moderate temperatures with high humidity
Explanation: High humidity and moderate temperatures are ideal
conditions for carburetor ice formation.
9. What document must always be carried aboard the aircraft?
A. Maintenance logbook
B. Pilot logbook
C. Airworthiness Certificate
D. Weight and balance worksheet
Answer: C. Airworthiness Certificate
Explanation: The Airworthiness Certificate must be displayed and
carried in the aircraft.
10. What is the purpose of the magnetic compass?
A. Measure altitude
