THROTTLE - se
e figure 7.6.3
The THROTTLE has two operating modes : thrust mode and condition mode.
- Thrust mode
The THROTTLE is in vertical position. It modulates engine power from full
reverse to max power.
Engine running, the throttle 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 THROTTLE forward.
▲ CAUTION ▲
Do
not move the cockpit THROTTLE into the propeller reverse position
or damage to the linkage will result.
Reverse may only be selected with engine running and propeller
turning.
Any rearward effort on the THROTTLE, past the idle stop, may
damage or break the flexible control cable.
▲
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.
