Reality Check please........
Airbus vs Boeing..........and all that crap.......
In the light of the A300 accident all manufacturers provided guidance on the use of the rudder, as cyclical use of it could greatly exceed design parameters.
Think about it - it is a huge control surface designed to give way more control moment than any other - aileron or elevator; to cater for an extreme situation, where at minimum control speed, Vmca, with one engine at full thrust and the other at idle, directional control can be maintained.
It was never considered in the design that the structure would have to cope with full deflection in one direction rapidly followed by the opposite. To go rapidly from Full Scale Deflection in one direction to FSD in the other creates a force way beyond the design parameters.
The NTSB and all other agencies associated with the A300 accident came to the same conclusion, that sufficent loads were generated in the manouevres involved that resulted in the fin detaching itself from its mountings. If replicated in just about any other transport category aircraft, the result would be the same.
The repercussions are simple - we (professional pilots) all fly aircraft that have limitations on handling. Rudders have the greatest amount of gearing compared with other surfaces and have the highest risk of being over extended. Full control input followed by full opposite input may exceed the structural integrity of the aircraft.
I think it is quite amazing that such lessons are only being learnt in the 21st century- one hundred years after we first learnt to fly.
