Nobody advocates "doing nothing with the collective."
Simply this:
First: sharpish cyclic input to raise the nose and get an upward vector going.
Second: smoothly lower the collective.
Third: (and i should have put this bit in before, but thought it was pretty obvious) don't let the attitude stay above that for auto speed - be it 60, 65, 75 or whatever. As the airspeed bleeds back and the trajectory arc turns back into a descent, relax the attitude to hold auto speed, and come on down.
RRPM always seemed to stay in the green, but usually by that time, the eyeballs were firmly outside on the height/landing area.
Remember why the lower shaded area of the Danger/Avoid Area is there.
Too fast, too low, too late, too bad, two bodies.
Funnily enough, an S76B doesn't have a lower area, but an A model does. Not sure why, perhaps because it has a higher permissible run-on speed and higher max speed for using brakes? Nick?
