aguadalte, moving throttle levers didn't prevent the F-OGYP crash.
dvv, you're right (I must concede), but there is a slight difference that is very important for this case: in the F-OGYP accident, the pilot was hand flying with Auto-Throttle OFF. The behavior of the levers is the same on both systems,
when disconnected. I'm comparing the behavior of Auto-Throttle vs ATS,
when connected. And as far as I know (the last a/c I flew with Auto-Trottle was the A310-300) when the Auto-Throttle is ON, if you retard one of the levers, the other tend to follow the retarded one. You have to
positively (in the sense that this is an intentional decision) disconnect the Auto-Throttle to bring only one lever to the retard position. And that makes all of the difference between both systems...
