1.
If engine power is increased with the propeller lever in the constant speed range, rpm
increases, then: C. The Governor weight move out, blade angle increases, rpm decreases,
weight move in.
2. Concerning an aircraft with a fixed pitch propeller, propeller efficiency will be: Low at both
low and high speed, and highest at cruising speed .
3. Propeller Blade angle is: A. The angle between the blade chord and the plane of rotation.
4. The geometric pitch of a propeller is: A. The theoretical distance the propeller would move
forward in one revolution at the blade angle set.
5. A right hand propeller: Rotates in a clockwise direction when viewed from the ear.
6. The greatest stress on a roating propeller occurs: D. At the root.
7. As the aircraft accelerates down the runway, the angle of attack of a fixed pitch propeller:
Decreases.
8. A propeller which is winmilling: A. Rotates the engine in the normal direction and gives drag.
9. The alpha range of a variable pitch propeller is betwenn: A. Feather and flight pitch stop.
10. A hydraulic accumulator may be fitted to a single acting propeller to provide pressure for: B
Unfeathering the propeller .
11. The blade angle: decreases from root to tip.
12. Propeller torque results from the forces on the propeller: C. caused by the airflow, giving a
moment around the aircraft’s longitudinal axis.
13. If the RPM and throttle levers of an engine with a Variable Pitch propeller are not moved
with increasing TAS, the angle of attack: D. Remain the same.
14. An aircraft with a fixed pitch propeller goes into a climb with reduced IAS and increased
rev/min. the propeller: Angle of attack will increase.
15. When the CSU is running on speed: The governor weight centrifugal force balances the CSU
spring force.
16. A propeller blade is twisted along its length:B.To maintain a constant angle of attack from
root to tip of the blade.
17. During the take off run, a fixed pitch propeller is: A. At too coarse an angle for maximum
efficiency.
18. The propeller blade is twisted: D.To even out the thrust force along the length of the blade.
19. In the case of an aircraft with a fixed pitch propeller, an increase in RPM during the take off
run at full throttle is due to: A more efficient propeller blade angle of attack.
20. An auto – Feathering system senses:D. Low Torque.
21. If it is required to increases the R.P.M. of a variable pitch propeller without moving the
power lever, the propeller level must be moved: Forward, the governor weights move
inwards, blade angle decreases.
22. The beta range of a propeller is from:D. the flight fine pitch stop to the reverse pitch stop.
23. The trust force of a propeller producing forward thrust: A. Tends to bend the propeller tips
forward
24. Propeller torque is: The turning moment produced by the propeller about the axis of the
crankshaft.
25. The blade angle of a fixed pitch propeller would be set to give the optimum angle: B. During
the cruise
26. The angle of attack of a fixed pitch propeller: Depends on forward speed and engine
rotational speed.
27. The blade angle of a propeller is the angle between: D.the propeller chord and and the plane
of rotation of the propeller.
28. The CSU incorporates an oil pump. Its purpose is: To increase the engine oil pressure to a
higher pressure to operate the propeller pitch change mechanism.
29. The purpose of the centrifugal feathering latch on a single acting propeller is to prevent:
C. The propeller from feathering on shut down.
