Another true but worthless statement.

Hmm... Is it a true statement though? The King autopilots (and the
S-Tec range AFAIK) both are designed such that they use pitch servos
to reposition the control surface (elevator or stabilator) to affect
a change (climb, descent) and have inbuilt feedback generators to tell
the trim servo to actuate such that it removes the load from the
surface at its new position. That seems to be at least two systems
who's basic design incorporates a methodology to actively relieve
control pressures.

You are being realistic and practical in your interpretation.

He is being a pendantic, semantic game playing, asshole in he's interpretation.

Ah. Yes, he does have the propensity to do that doesn't he. And he
changes the pedantry context even within the thread he's ruining. Like
in this one, yea, autopilots control aircraft but his statement that
"no autopilot is designed to relieve control pressures" in the context
of the subthread could be parsed as "no autopilot is designed (with a
mechanism) to relieve control pressures", rather than the ultimate
design goal of an autopilot system, and he switches back and forth to
suit whichever asinine argument he's proffering at the moment.....
