I have read on other forums that most GA single engine aeroplanes props would revert to fine pitch, is this the case with 182s??
Any thoughts on this would be greatly appreciated!
cheers
It's in the POH. Here you go:
CESSNA MODEL 182T NAV III GFC 700AFCS
PROPELLER
SECTION 7 AIRPLANE AND SYSTEM DESCRIPTION
The airplane has an all metal, three-bladed, constant speed, governor regulated propeller. A setting introduced into the governor with the propeller control establishes the propeller speed, and thus the engine speed to be maintained. The governor then controls flow of engine oil, boosted to high pressure by the governing pump, to or from a piston in the propeller hub. Oil pressure acting on the piston twists the blades toward high pitch (Iow RPM). When oil pressure to the piston in the propeller hub is relieved, centrifugal force, assisted by an internal spring, twists the blades toward low pitch (high RPM).
