The pilot of 447 was unaware that the co-pilot had been holding back on the stick for the entire descent. He knew what to do when he discovered that. But, that came too late.I was not referring to hand flying. I’m referring to the skill set that should have let the crew of Air France flight 447 recognize, and safely recover from, their stall. I’m referring to the skill set that would enable a flight crew to recognize that a trim system or a stick shaker is not operating properly. I’m assuming that if they recognize that, they will know what to do.
