02 PROPELLER CONTROLS
Hamilton Standard hydromatic, fully feathering propellers are fitted. Constant speed levers
project downwards from the throttle quadrant, with the throttle friction nut controlling their
stiffness of operation.
Feathering buttons are mounted on the front of the quadrant, and are operated by pushing
upwards. The buttons hold in electrically to feather, but must be checked to have 'popped'
out at the end of the feather sequence and should be pulled out if necessary. They must
be held in during the unfeathering sequence and positively pulled out once the engine
starts and before 1OOO RPM is reached.
03 PROPELLER OPERATION
The Hamilton Standard propeller uses engine oil pressure and aerodynamic forces to
increase pitch, and boosted engine oil pressure to reduce pitch. The pitch levers in the
Flight Station connect directly to the Constant Speed unit on the front of the engine via
cables and pulleys.
The movement of the cables changes the enclosed gyroscope balance so directing oil
pressure to or from the propeller pitch mechanism. The Governor Pump supplies the
boosted engine oil pressure.
Propeller pitch changes, allowing more or less RPM to develop, and the Governor
gyroscope is returned to a balanced state.
When feathering or unfeathering takes place the oil ports are manually selected in the
CSU by positioning the pitch lever at minimum RPM (Full Coarse). A feathering pump is
