Add to the AF447 A330, the Colgan Air crash at Buffalo, NY and the XL A320 at Perpignan. You don't have to look too far to find evidence that automation is relied on far too much. It's not only about the of erosion of manual flying skills but also recognising and diagnosing the situation the aircraft is in. If pilots were exposed to situations in aerobatic aircraft where they could experience the symptoms of stall, spin and UPs and then execute correct recovery techniques, IMHO they would be able to bring this experience to the fore when confronted with the seemingly incredible circumstance of loss of control in a complex modern airliner. In the cases of the AF447 A330 and the XL A320 , these types have protections to prevent the stall:WHEN THEY ARE FULLY FUNCTIONING. When all the holes line up in James Reason's Swiss cheese accident model (Wikipedia if you haven't heard of it), it is then down to the pilot to prevent the accident. Sadly, these accidents are showing that the pilots are not doing so.
