Questions and Answers
What is the primary method used to maintain constant RPM in a propeller?
What is the primary method used to maintain constant RPM in a propeller?
- Increasing the propeller diameter
- Altering the engine power output
- Changing the blade angle (pitch) (correct)
- Adjusting the balance of the propeller
What happens to the RPM when the pitch of the propeller is reduced?
What happens to the RPM when the pitch of the propeller is reduced?
- RPM remains unchanged
- RPM decreases due to higher brake moment
- RPM is completely independent of pitch
- RPM increases due to smaller brake moment (correct)
When can the propeller governor not maintain constant RPM?
When can the propeller governor not maintain constant RPM?
- When RPM is correctly set via rods
- When engine power is significantly reduced (correct)
- When the propeller control lever is set to idle
- When the propeller is set to fine pitch

Flashcards
Variable Pitch Propeller
Variable Pitch Propeller
A propeller whose blade angle (pitch) can be adjusted to maintain a constant rotational speed (RPM).
Propeller Governor
Propeller Governor
A device that automatically regulates propeller RPM by adjusting blade pitch based on engine RPM.
Centrifugal Regulator
Centrifugal Regulator
Part of the governor, these flyweights sense engine RPM and regulate hydraulic oil flow.
