I, along with a lot of other pilots on this thread, believe overiding an autopilot or autothrottle not doing what you want it to do is improper and should never be done on an Airbus because of Airbus policy.
I guess that is why I always flew Boeings because they were just an airplane and you could overide anything you chose to overide. I know I can correct a situation hand flying but Airbus says, NO, push this button. I think Airbus has made their pilots into flying robots. AF447 demonstrated this when all they needed was one pilot who knew how to hand fly but he was taking his break. Maybe he should have stayed in the cockpit to take care of the children of the magenta line. Pilots should always be pilots and not let the company make you into a computer operator.
