We all know how easy it is to recover from a stall. All pilots learn that before they are released for their first solo. You learn stall recovery in the first 10 hours of your PPL flight training.
What pilots are now experiencing with complex aircraft is a new situation where, due to the complex design nature of their aircraft, they instantly don't know what the aircraft itself is doing. So in an abnormal situation, as in the one which lead to AF447, we have the situation where 3 qualified pilots were baffled with what was happening to the aircraft. You have about 3 to 4 minutes to work out what's going on, and then to deal with it, or else it's game over.
Would I be right in saying, AF447 was the first instance, of a deep stall ever experienced by a FBW Airbus aircraft? No-one has ever been in a similar position before? If the aircraft had been a non FBW A300 or A310, would the outcome have been different?
