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.
