budgevheli,
This conversation is intellectual chess on what to do in a situation that in my opinion a pilot should never allow to happen.
I have seen the R22 Nr at 78% doing autos in the training environment, and it recovered promptly by waiting. No flare, turn, push or pull. I never want to see it there again though, and I think the pilot (that was me!) is to blame by letting it get that low. I learnt from that.
I wonder just how close the rotor was to stalling back then, but in my mind this conversation is talking about 75% Nr or less, ie critically low Nr.
And yes, I'm as concerned as you are that someone might take this speculation on board somehow and in confusion deviate from what they have been trained to do when the blood is pumping.
Stick to the training! Pprune is a great source of info, ideas, and increased awareness. How people choose to interpret that and what course of action they ultimately take is up to them eh?
