Coordinated turns without rudder, and autopilots

Then you should know that the vertical stab can't prevent yaw, it can
only help eliminate yaw once it occurs as it can't provide any restoring
force until some degree of yaw occurs. A rudder an prevent yaw from
occurring in the first place. Fundamental difference here.


Nope. In most flight regimes if you displace the rudder you are
generating yaw not preventing it. What you are trying to wrap
your brain around is that you can use the rudder to accellerate
the responsiveness of the vertical stabs natural tendencies,
but by your own admission, in coordinated flight the stab is
streamlined.

No, I'm trying to get you to wrap you brain around the fact that the
rudder can act preemptively to prevent a departure from coordinated
flight. The vertical stab can not act preemptively. Fundamental
difference.

I have plenty of good books and practice on the subject.

Me too.

You're wrong.

You should find an aeronautical engineer and find out how
planes are designed to work.

..Well...you build them, I will fly them and we need the rudder to
coordinate turns particularly but not exclusivly with ailerons.
