Except in an airplane where the trim system moves the horizontal
stabilizer instead of a trim tab. In that case, there is no feel
feedback to the yoke. One must release the pressure and see if the
airplane attitude remains where desired.

This makes no sense to me. If the airplane attitude remains "where
desired" (I presume that is the same as where you put it, using
pressure) when you release the pressure, then the pressure isn't doing
anything. How do you fly such an aircraft?
