Amazingly the A330 had enough pitch down authority to unstall up to some horrendous A of A, and had the crew only persisted in a nose down demand they might have recovered, though the nose down attitude needed was probably beyond their imagination. Some very courageous AB test pilots tried it out well into post stall (20 degrees or so from memory) and lived to tell the tale.
I just had another look at BEA's AF447 final report, but can't find any mention of such test flights. Are they on the record somewhere?
