Could it be a case of Vestibular/somatogravic illusions? ...Anybody wants to comment?....
We did; in posts #96, 98 & 99.
All this *** about somatogravic xyz or flap fail/fuel imbalance (certain balls) is all very well The most likely cause is quite simply overpitching due to a mishandled g/s and botched recovery, I'd be astonished if it were anything else.
I think you are correct in saying that the overpitching and botched recovery is the direct cause but it oversimplifies the wider cause that needs to be recognized. An aircraft should recover within the available altitude considering that a high power setting was already achieved. The stall would be broken quite quickly. The only reason to continue to pitch forward is because the pilot thought that he was still increasing his pitch. He did not believe his instruments. Look at the report linked in post #96. In the Annex is an excellent explanation of somatographic illusion. The rapid pitch up or the stall did not cause the illusion. It usually begins when an upward pitching motion is abruptly checked around 20-30 degrees nose up, so in this case it began when he tried to recover from the stall. This is what sends the semicircular canals spinning and causes the false pitch up sensation.
It is impossible to demonstrate this effect in a simulator during training due to the lack of 'g' effects. This pilot may not have even been aware of the phenomenon judging by the previous comments about how the training and qualifications are achieved.
