Propeller
Airplane is equipped witha composite five-bladed, constant-speed and full-feathering
pro
peller.
Regulation
Propellergovernor located on engine maintains rotation speed to the nominal value of
2000 RPM. Regulation is obtained through propeller blade pitch variation :
counterweights drive propeller blades toward high pitch (low RPM) whereas oil
pressure delivered by governor drives back blades toward low pitch (high RPM).
Propeller governor allows feathering either by voluntary pilot action via THROTTLE
(Condition mode) or automatically in case of engine failure or shutdown.
Propeller reverse pitch allows reduced taxiing speed or landing roll. Change from idle
to reverse position is performed with THROTTLE (Thrust mode) - refer to paragraph
Engine controls.
