Default Coordinated turns without rudder, and autopilots

How do autopilots make coordinated turns even when they cannot control the
rudder?


As others have posted, most lightplane autopilots don't adjust the
rudder for adverse yaw when turning, so you do get a few seconds of
slightly uncoordinated flight. However at normal cruise speeds this
creates no hazard or discomfort.

If flying close to stall, the autopilot should be turned off even for
straight and level flight. If the airplane is on the verge of
stalling and starts to turn because of engine p-factor or any other
reason, the autopilot will attempt to correct with aileron. This may
actually induce stall on one wing, producing sudden wing drop and a
potential spin.
