Default Coordinated turns without rudder, and autopilots

An unwanted side-effect of aileron operation is adverse yaw — a
yawing moment in the opposite direction to the turn generated by the
ailerons. In other words, using the ailerons to roll an aircraft to
the right would produce a yawing motion to the left. It is caused by
an increase in induced drag due to the greater effective camber of
the wing with a downward- deflected aileron, and the opposite effect
on the other wing. Modern aileron systems have minimal adverse yaw,
such that it is barely noticeable in most turns. This may be
accomplished by the use of differential ailerons, which have been
rigged such that the downgoing aileron deflects less than the
upward-moving one. Frise ailerons achieve the same effect by
protruding beneath the wing of an upward deflected aileron,
increasing drag on that side. Ailerons may also use a combination of
these methods.


Except I do see adverse yaw in turns in my (simulated) Baron,


It's not a Baron, fjukktarfd, it;s a comnputer.
