controllable-pitch propeller

controllable-pitch propeller
A propeller whose pitch can be altered by the pilot in flight. Unlike in a constant-speed propeller, where the governor automatically controls the pitch, here the pilot carries out the pitch adjustments. Takeoff is made with a low blade angle, so that the engine develops maximum power. The blade angle is increased during cruise, so that the engine operates at a slower and more economical speed.
