Sasless,
My 60% has nothing to do with the other thread, I'm on about post impact.
To put it in its place;
Nr & N2
60% is idle with twist grips on the red buttons.
75% is normal ground idle (twist grips in normal detent'd position)
97% is flight idle
100% is flight idle with high Nr selected
103% is flight idle on application of collective
100% is flight above 55kts
103% is flight when reducing below 50kts
With these figures, instead of jumping down necks, please remember that when the Nr is above N2 it is not being driven by the engines. Normally, with the tr issue as previously described, the twist grip is rotated to the stop. The engines then wind down to 60% and the MRGB is then disengaged. As there was no rotation of the main or tail rotors on impact, the pilot must have fully wound off the twist grip, beyond the button, otherwise when the Nr reduced to 60% they would be driven once more by the engines ... as I said in my post 1326 that you happily criticised.
