Thanks for your input, Simon.
The PDF quotes:
"The mechanical input to the rudder servo control units is limited by the position
of the Rudder Travel Limitation Unit ( TLU ). The input rods will also act
against the Artificial Feel & Trim Unit."
Which does infer that input (which is coming from rudder pedals) is in fact limited. Perhaps the limiting is performed by the artificial feel unit and not directly by the RTLU?
Anyway, please don't take this the wrong way, but I am not yet fully convinced by your statement. This skepticism is also based on some false factual statements you made in the FBW control law thread (but you sound very convincing :-) ).
