Autopilot fighting for control

The Cessna instructors are probably showing that the servos
can be over-powered with pilot muscle, no reason to lose
control. But I'm sure they also teach the location of CWS,
the trim switch, the red disconnect button and the A/P CB
and avionics master.

There's no CWS on the KAP140 install in the NAV3 equipped Cessna line.
Probably on the Mustang when it comes out, but not the SEPs.

It's been a few years so things might be different now, but IIRC, the
class doesn't teach leaving things in NAV mode to fly procedure turns,
but teaches doing a partial-panel approach by selecting wing-level and
flying it that way. Personally with a working aircraft I always fly a
procedure turn w/ autopilot by changing it to HDG mode, flying the
procedure turn with the bug, and then re-arm APR on the inbound
intercept.

I've got CWS on my 55X. Frankly, I never use it.

That's what works for me. On the 55X, you can HDG+NAV+APR
at the same time and it holds the heading until the needle comes
alive (if you just NAV+APR, it may make a more agressive turn
towards the course).

Yea, same on the KAP140. I use HDG+APR and try for a 30-40deg
intercept angle. Seems to work.
