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?
