Thanks for your reply Ghengis. Some good food for thought. Might I ask what you do in the scheme of things?
One question
"For a given wing configuration (i.e.flaps, slats, etc. left alone) an aircraft will always stall at the same AoA regardless of weight and speed, but not at the same stick position. Change the flap / slat settings and the stalling AoA will change too."
Can you clarify this statement... I have been always taught quite firmly that the Critical angle of attack never changes. By extending flap you are simply moving the position of the chord line (the line between the centre of curvature at the leading edge and the trailing edge). You are not causing the wing to stall at a different AoA you are only changing the AoA for a given attitude.
