Rat 5
All this chat about aerobatic and unusual recovery training is, very sad to say, pie in the sky.
On the contrary, I found the unusual attitude sim session quite illuminating. With practice, I could recover from being totally inverted to normal flight in less than 3,000 ft. Might have spilled a few G&Ts, but it was eminently recoverable.
Likewise the high altitude stalling was interesting too. With the engines at full chat (as commanded by the a/t) it was almost impossible to recover from the stall. And at cruise power, full forward control deflection was required. It was useful to learn that the standard light aircraft nod into a recoverable descent just did not happen, and the aircraft would just pancake down almost tail first - just as AF447 and this one did.
