Yes, my understanding is that a bank causes an airplane to slip, which
then causes it to weathervane into the wind. Why do you ask? Is there
something I am missing?

Sure, but that still does not explain why the airplane turns. A
horizontal component of lift will make the airplane side-slip, not
turn. It is the stability (weathervane effect) that makes the
airplane turn.

By definition, the 'weathervane effect' occurs because air exerts

more
pressure on one side of the object (aircraft) than the other - same
definition as slipping. Therefore, are you are asserting that an
aircraft turns because it is slipping? More over, it will only

turn
if it is slipping?

Think of the space shuttle. If you fire rockets horizontal to the

flight
path, the shuttle will slide sideways. It will not turn the nose

towards
the direction of travel. An airplane turns because it wants to point

the
nose into the relative wind.


I understand that, but you never answered my question: "Are you

asserting
that an aircraft turns because it is slipping (weathervaning)?"
