A lot of pilots on this site seems to have this a fetish about engine failures and getting the collective down quickly !!! Firstly dare i say it, but most of these guys are much more likely to bang it into auto ...dump the lever etc for something other than a flame out. They will do it with partial loss of power, lights coming on or even just a thumpthrough the pedals
The facts are that an engine failure just as you are hot dogging towards the cliff are one in a million and even if that did happen I for one would NOT be looking to drop the lever!!! The guy in the vid knows that he has ample time to do that because the first thing he will do is a sharp flare to a) stop belying towards cliff and b) to gain altitude. He may even use MORE collective to keep rrpm down. Then he will do a torque turn and auto down safely.....hopefully. Keeping collective up and using cyclic to convert speed to hight does not seem to be taught now but is the norm for low flying. IF you have your hand ON the collective you may be conditioned to dump it.......then you do crash & burn. IMHO
