i think john was making it clear that aileron defection doesn’t affect the aoa elsewhere on the wing, only the bit in front of the moving surface, increasing or decreasing its aoa and lift coefficient. of course, during the turn the aoa varies from wing root to tip, but this is due to the difference in turning radius (and therefore airspeed).
re: the wing incidence angle changing from root to tip thereby changing the aoa - not quite sure what you mean by that, but if you're referring to the washout built into the wing structure, that is a constant, for all intents and purposes. as aoa is relative to the aircraft's reference line (which applies to all wing stations - irrespective of washout) this effect is bit of a red herring here. thats if i correctly understood what you were getting at - the term 'incidence angle' sometimes means different things to different people.
