Blind obedience to printed checklists and the Pavlovian response some regimes demand "KILL" pilots. Have had the luxury to sit in the back of sims watching pilots in training do that very thing. One operator insists pilots perform an immediate landing if anything goes awkward while at a hover.....two of their senior TRE's demonstrated the wisdom of that in a 212 Sim ride.....failure was high side gov fail that does not respond to throttle. They lowered the collective and tried to sort the thing out on the ground.....needless to say...the N-r went bonkers....and while they fiddled around.....the sim finally elected to self destruct the engine......teaching point is that a printed checklist does not....and cannot cover all situations.
Fly....think....act.....
Lowering the collective in a Robbie or other low inertia machine is probably not a bad move.....but once again......you make a wrong guess and it all gets ugly quick!
