can you explain this feature basically? when do we need to use this? should we use this in normal flight conditions?

The function of the governor is to maintain the correct engine rpm at any given collective position, making sure that the rotor rpm doesn't drop during any stage of flight. You can put the governor switch to manual but at that position you have to work the throttle manually at every change of the flight controls. In normal conditions the switch is left in auto mode. Please correct me if I am wrong, all.

I flip the governor to manual to pick up when the load is heavy (Guns/Rockets/Gunners)

After pick up I climb to 75-100 FT AGL ( depending on terrain )

Pitch forward and wait until till I achieve 65 KTS before returning it to Auto.

Chapter 3 will help.

It's an overspeed governor. It prevents N2 overspeed.

 

The droop compensator provides a mechanical linkage between the governor speed selector and the collective stick. If a sudden power demand occurs the fuel valves will open up a little extra to compensate.

 

A governor failure in the Huey will cause N2 overspeed

A droop compensator failure will cause a sudden loss of RPM if pitch is increased too fast.

 

Not quite your modern EEG, but it works.

And you EGT with when doing this climbs to what numbers and for how long?

Thanks Frett. I need to study the manual better. :smilewink:
