I well remember on my CPL IR, fighting to maintain a positive rate of climb with a one-engine-out C310. And that was only me and the examiner.
If I'd actually had a full load of passengers I believe I would have had to go down. But they never taught you that, so surely in a real situation you would do everything else but that, ie finish up stalling?
That's not the point here though. This is Kegworth all over again.
What they don't teach you is, in an emergency, do nothing . The game is on your checks to move your hands at the speed of light and talk like a 33rpm played at 78. It's wrong. It doesn't work in normal life and it shouldn't be the standard for pilots. I suspect an RAF influence here.
Perhaps we should forget CRM and concentrate on cool, calm decision making techniques.
