From the thread "AAL 300 Accident" in Rumours and News:

"Ronald Hess, .... is an aeronautical engineering professor at the University of California-Davis.

"But after the A300-600's rudder begins to move, it requires far less pressure to swing the rudder an equal distance than on other types of jets.
At 290 mph, a pilot who had begun to move the rudder need only add 10 pounds to the pedal to swing the rudder all the way to one side.
By comparison, the similar-sized Boeing 767 requires 63 pounds of additional pressure to move the rudder as far as possible.
1) Is that true (10 lbs vs 63 lbs) rudder force for full deflection?
2) If it is true, is that a problem ?
3) If it is a problem, then is there a flaw in the certification regulations / process ?
