AOA varies uniquely with coefficient of lift. Maximum lift does not occur at the critical angle, the maximum coefficient of lift does. The stalling airspeed is a function of many things like gross weight, bank angle, and CG. But the aircraft always stalls at the same critical angle. This is because the stall is defined as the point at which the coefficient of lift is at its maximum (the critical angle of attack). I hope this helps clear up some technical points.

At a large aircrat manufacturer, the critical angle of attack is determined by flying straight and level and slowing the airspeed at at a fixed rate. When the g meter first indicates less than one one g, that's the critical angle. Of course this is done at different gross weights and CGs but in theory the critical angle for all test flights should be the same. —Preceding unsigned comment added by JamesBFrantz (talk • contribs) 05:59, 21 October 2009
