Which statement best describes the operating principle of a constant-speed propeller?
Which statement best describes the operating principle of a constant-speed propeller?
  • A high blade angle, or increased pitch, reduces the propeller drag and allows more engine power for takeoffs.
  • As throttle setting is changed by the pilot, the prop governor causes pitch angle of the propeller blades to remain unchanged.
  • The propeller control regulates the engine RPM, and in turn, the propeller RPM.
