Power control lever
The power control lever is linked to fuel control unit. It modulates engine
power from full reverse to takeoff.
Engine running, the power control lever rearward displacement, past the lock
using the detent, allows to control :
-- the engine power in the Beta range from idle to maximum reverse,
-- the Beta valve to select the propeller pitch in reverse.
Return to idle position is accomplished by pushing the power control lever
forward.
CAUTION
DO NOT MOVE THE COCKPIT POWER CONTROL LEVER INTO THE
PROPELLER REVERSE POSITION OR DAMAGE TO THE LINKAGE
WILL RESULT.
REVERSE MAY ONLY BE SELECTED WITH ENGINE RUNNING AND
PROPELLER TURNING
When engine is shutdown, there is no oil pressure in the propeller and the
feathering spring locks the Beta ring and the propeller reversing interconnect
linkage on the engine.
All rearward effort on the power control lever, past the idle stop, may damage
or break the flexible control cable.
Propeller governor lever
The propeller governor lever activates the propeller governor located forward
of the engine to select and maintain any propeller speed between 1600 and
2000 RPM. This lever allows propeller feather. Changing from normal range
to feather position requires ”FEATH” stop by moving lever toward left side
and back. The lever being locked in feather position, unlocking requires
moving the lever toward left side and forward.
Condition lever
The fuel condition lever is linked to FCU. It can be positioned to cutoff, idle
LO / IDLE or idle HI / IDLE. Change from idle LO / IDLE to cutoff position is
only possible after having overridden the idle gate. To override idle gate, raise
lever and move it rearwards. If the lever is locked in cutoff position, unlocking
is performed by raising lever and moving it forward.
