And do you really think the Sim is accurately modelled with no Hydraulics
Well I don't suppose it is but it does represent a reasonably accurate aerodynamic model of the aircraft and I suspect that the way it behaves with the hydraulics switched off is not a million miles away from how the aircraft would behave under similar circumstances. I have had a go in a 320 sim and although you can fly it around the sky on engine thrust fairly easily it becomes pretty much impossible once you try to maneuver for an approach and landing. My admiration for the the two (that I know of) crews that have pulled it off for real is immense. Not just an Airbus problem of course, every Boeing from 747 onwards has needed hydraulic power to move the surfaces, the 737 was last one with manual reversion.
