1. What is the primary source of lift for a gyroplane?
A. Propeller thrust
B. Unpowered rotor blades
C. Fixed wings
D. Engine exhaust gases
Rationale: In a gyroplane, lift is generated by unpowered rotor
blades that autorotate due to the aircraft's forward motion.
2. What term describes the rotation of the rotor blades caused by air
moving upward through the rotor system?
A. Propulsion
B. Autorotation
C. Induced drag
, D. Gyroscopic precession
Rationale: Autorotation occurs when upward airflow through the
rotor system causes the blades to spin freely, generating lift.
3. Which component provides forward thrust in a gyroplane?
A. The propeller
B. The rotor system
C. The tail fin
D. The cyclic pitch control
Rationale: In a gyroplane, an engine-driven propeller provides
forward thrust, while the rotor provides lift.
4. During autorotation, the rotor blades are driven by:
A. The engine
B. The cyclic control
C. The upward flow of air through the rotor disc
D. The rudder
Rationale: Autorotation occurs because the air moving upward
through the rotor disc drives the rotor blades.
5. Which type of airframe is most commonly used in light-sport
gyroplanes?
A. Wooden
B. Steel monocoque
C. Tubular aluminum or steel frame
D. Composite sandwich shell
, Rationale: Most LSA gyroplanes use lightweight tubular metal
frames for strength and simplicity.
6. The thrust line in a gyroplane should ideally:
A. Pass below the center of gravity
B. Pass above the center of gravity
C. Pass close to the center of gravity
D. Be perpendicular to the center of gravity
Rationale: A thrust line near the center of gravity ensures stability
and reduces pitch oscillations.
7. What is the function of the pre-rotator in a gyroplane?
A. Provides lift during flight
B. Spins up the rotor before takeoff
C. Controls yaw
D. Acts as a brake for the rotor
Rationale: The pre-rotator is used to bring the rotor blades up to
speed before takeoff to shorten takeoff distance.
8. What happens if the engine fails in a gyroplane during flight?
A. The aircraft stalls
B. The rotor stops spinning
C. The aircraft continues to autorotate and can glide safely
D. The propeller provides lift
Rationale: Gyroplanes can glide safely in autorotation even if the
engine fails, as the rotor continues spinning.
, 9. The cyclic control in a gyroplane changes:
A. Engine power
B. The pitch angle of the rotor blades cyclically
C. The tail rudder position
D. The propeller thrust
Rationale: The cyclic control tilts the rotor disc by changing blade
pitch cyclically, controlling direction.
10. The rudder in a gyroplane is primarily used to:
A. Change altitude
B. Control yaw
C. Control roll
D. Adjust lift
Rationale: The rudder controls yaw, or left-right movement, by
changing airflow over the vertical stabilizer.
11. What determines the rotor blade’s lift at a given airspeed?
A. Propeller RPM
B. Angle of attack and airspeed
C. Rotor hub angle
D. Weight of the gyroplane
Rationale: Lift depends on airspeed and the rotor blade’s angle of
attack.
