An instructor in the US recently gave me some hover auto training in an R22, which is throttle off, right pedal, let it settle, pull up lever. Fairly simple...
I failed to completely turn the throttle fully into the detente and when I pulled the lever the correlator increased the throttle enough to get the revs back into the governed range, the governor took over and picked up the revs. This led, of course, to unanticipated right yaw and lift. The ship bounced off 2 skids, yawed substantially, but the instructor recovered it and we tried again after my change of underpants, but he kept the governor on for the further training.
My question is: do instructors more commonly do this training with governor off? I can't see any real benefit of governor on - if you turn off the throttle at that height, you're going to hit the deck and the risks of having governor on are that exactly what happened to us will occur, and an R22 bouncing off skids is not a great place to be!
