DCS: AH64D Apache - How to autorotate

This video demonstrates how to autorotate the DCS AH-64D Apache and a common problem you might encounter when trying it yourself.

i love the thumbnail lmao

Well done!! I note that you had no vertical velocity or height indication on your HDU during the autorotation until you were nearly on the ground. Yet all your other avionics seemed to be working fine.

Yes, the reason is that the power went off (at 4:05) for a few seconds after I cut off the engines. I am not sure, how the whole power system in the Apache works (have to read the manual), but the generators also seem to be tied to the rotor RPM. However, I don't know yet, why some of the systems came back, while others didn't. Any clue?

@@wychmaster7450 No, not really. If the generators initially spooled down then all the avionics should have gone off. I think only the small front display is supported by battery power.

@@wychmaster7450 when the main rotor transmission went below 77 nr the 85-tooth gear sprag clutch was disengaged, the sprag clutch provides shaft power to the accessory gearbox that generates ac power, the clutch was engaged again when main rotor transmission whent up again.

Autorotation doesn’t really work yet in this module. All of the SMEs say the blades have too much drag

Thanks for the info. As I said at the beginning of the video, changes to the module might render this video useless in the future. However, until then, it might save one or two virtual lifes ;)
