No, I'm wrong! The AofA is measured as that angle between the relative airflow and the chord line of the wing. The chord is a straight line joining the leading and trailing edges of the wing and as such will clearly give a higher AofA for a given NOSE ATTITUDE with flap deployed. Although the wing shape is now different it should stall at roughly the same AofA but at a lower nose attitude.
Who's digging a hole now!
