I have a strong suspicion the simulator is the simulator, and real life will cause a considerable surprise. It would be interesting to hear if manual reversion has been sampled in development and maintenance flying with non-Boeing staff pilots, and how similar it is felt to simulation. The impression I get is the aeroplane deviates in roll and pitch, and it is impossible to fly steady state. I think an approach would be difficult. True, it's better than nothing (like the 757), but I always felt I could get it near a runway, but at what ROD and position would be down to luck only. I believe it has never been done in anger?
