Automatic feathering is initiated b

Automatic feathering is initiated by means of a torque switch. Whenever the power levers are
positioned above the idling range, and the engine torque falls below a specified amount, the
torque switch closes and completes a circuit to the feathering pump and the valve-lift solenoid in
the PCU. The solenoid directs oil to the valve-lift piston, which raises the governor valve, and
opens the oil ports from the feathering pump to the front of the pitch change piston, thus
feathering the propeller.
