Wino - "On the A300-605R there is NO rudder feel mechanism".
The A300-600 manual shows the rudder as having an 'artificial feel and trim unit'.
Somebody else queried A300 rudder pedal deflection. The manual says:
"2 independent Rudder Travel Limiting Systems (RUD TRAVEL) controlled by the Feel & Limitation Computers (FLC) progressively reduce the maximum rudder travel from +/- 30 deg below 165kt .. to +/- 3.5 deg above 310 kt." I don't know what that translates to in inches because there has never been any need for me to use the rudders in 2 eng flight (- and that includes a very nasty CAT encounter).
