Another example, about FADEC or equivalent power limiting systems for engines...
- to pick up on just one of your points, I think that if you study the findings of the Habsheim accident you will find that 'overboosting' would have made no difference to the outcome. It was spool-up time from idle that was the 'killer', and the fly-by-wire did its job perfectly in refusing to allow any significant raising of the nose due to lack of performance. Result - the a/c settled into the trees, but WINGS LEVEL. There is always the possibility that on a non FBW a/c the 'panic' pull back on the c/column could have caused a wing drop and roll which would probably have killed lots of pax?
The a/c kit said 'No'! We will never know whether there really WAS enough energy to lift the a/c those few feet.
