Default limit of trim = limit of travel?

trim has nothing to do with the movement limits on control surfaces.

Stealth,

This is not universally true. On the Douglas DC-6, for instance,
elevator "up" travel is limited by the elevator trim position. Dialing
in the last 5 degrees of nose up trim allows an extra 3 degrees of
elevator "up" travel. This was done to limit elevator "up" movement
with aft CG loading conditions.

Happy Flying!

ok you successfully cite the one instance possibly :-) I defer to your
knowledge of the obscure.

stops of the type I mentioned are a mandated requirement in my country
for the environment I play in.

Not nearly so obscure as you sugest. Aircraft with a fully trimming
stabilizer have a result result of adding to the effective elevator
authority--examples are the Piper Cub and all of the "straight tail"
Mooneys.
