1. What is the primary purpose of the ailerons on an airplane?
A) Control pitch
B) Control yaw
C) Control roll
D) Control lift
The ailerons are located on the trailing edge of the wings and control
the airplane's roll around the longitudinal axis.
2. What is the function of the rudder?
A) Control pitch
B) Control yaw
C) Control roll
D) Control speed
The rudder controls yaw, which is movement around the vertical axis,
helping to keep the airplane coordinated.
3. What is the standard atmospheric pressure at sea level?
A) 29.92 mmHg
B) 101.3 kPa
C) 29.92 inHg
D) 14.7 atm
,Standard sea-level pressure is defined as 29.92 inches of mercury (inHg),
or 1013.25 hPa.
4. What is the purpose of flaps during takeoff and landing?
A) Increase drag only
B) Increase lift and drag
C) Decrease lift
D) Increase speed
Flaps increase the camber of the wing, providing more lift at lower
speeds and allowing slower, safer takeoffs and landings.
5. What does VFR stand for?
A) Visual Flight Radar
B) Visual Flight Rules
C) Variable Flight Rate
D) Visual Flight Rules
VFR is a set of regulations under which a pilot operates an aircraft in
weather conditions generally clear enough to see where the aircraft is
going.
6. What is the purpose of the altimeter?
A) Measure speed
B) Measure pitch
C) Measure altitude
D) Measure fuel
The altimeter measures altitude by comparing atmospheric pressure to
a calibrated standard.
7. What is the primary flight control for pitch?
, A) Rudder
B) Elevator
C) Ailerons
D) Flaps
The elevator controls the airplane’s nose up or down around the lateral
axis.
8. Which wing shape produces the most lift at slow speeds?
A) Delta wing
B) Swept wing
C) Rectangular wing
D) Elliptical wing
Elliptical wings provide efficient lift distribution and are effective at
slower speeds.
9. What is the main purpose of the mixture control in a piston engine?
A) Control oil flow
B) Adjust fuel/air ratio
C) Control propeller pitch
D) Adjust carburetor temperature
The mixture control adjusts the fuel/air ratio for optimal engine
performance at different altitudes.
10. What is the definition of a stall?
A) Engine failure
B) Exceeding the critical angle of attack
C) Skidding in a turn
D) High-speed dive
A stall occurs when the angle of attack exceeds the critical angle,
causing loss of lift even if airspeed is high.
