Clandestino;
How would centrifuge training help pilot feel what AF447 crew felt is way beyond my comprehension, unless we are talking about stopped one.
That's really not what I was getting at. Put another way, if your butt sensors are only used to the usual about 1g, and you rarely pay any attention to the small inflight 'g' changes, then it seems rather obvious to me that neither of the crew noted the lack of 'g' change when applying NU/ND commands. This can only happen when you are on the ground, or as they were - stalled, and the aircraft response coming from just bigger or smaller 'barn door' effects.
The other clue was possibly the 'soft' rolling; certainly something you wouldn't expect with normal airspeed and AoA.
I know its easy to sit back and claim they were just a "clueless" crew and the chances of a similar result happening again is probably something approaching infinitesimal odds, but the "why" surrounding this event has to be addressed and corrected. So if that means crews need to experience the full range of acceptable 'g' forces in normal flight and those that could be expected in recovering from LOC, then so be it.
