One can also maybe think where the center of lift goes when one wing produces more lift than the other, and why that might give a rotational moment about earth-z. the control surfaces at the tail impart that force. Very small for sure, but I believe it's still there. Therefore, you could have an infinite number of center of lift vectors on a single wing. Angle b is the effective flow direction.
Now in straight and level, the rudder is in the same position as the elevator in the 90 degree bank, so it would be the one to point the aircraft into the center of the turn. In real life the aircraft would need to have an incline with the horizontal sufficient enough to produce enough lift via the body, rudder and vertical component of thrust to keep the aircraft level. If the wind sways a little sideways, it'll hit the rear part, bringing it back into line. PPRuNe Forums > Flight Deck Forums > Tech Log > Weathercock effect in turns Log in Username Remember Me?

Plus, based on what I know of things that weathercock, they're one piece and don't have "control surfaces". Aircraft on the ground have a natural pivoting point on an axis through the main landing gear contact points [disregarding the effects of toe in/toe out of the main gear].
