the four jet transports I've flown either had a rudder limiter or a placcard about control use. that plane would still be flying if it had a rudder limiter based upon speed.
All those jet transports have limiters which limit the rudder so that it is safe at any speed to apply
one full rudder input. Reversals are destroying any of those aircraft.
some pilots, myself included, think the problem was not in the pilots/copilots feet.
I agree, the problen was most probably more at the top end of the pilot/copilot...
No pilot is a normal state of mind would think, that he can safely do several full elevator reversals at that speed. So why should full ruder reversals be OK? On the other hand, would any pilot is a normal state of mind reverse the rudder at a 0.3 to 0.4 second frequency?
