AOA, L/D, Clmax and LE slats are what exactly?.... Been out of the
whole sport aviation for some time and just trying to grasp it all over

I've also noticed that many common airfoils actually have a
_lower_ stall AoA with flaps down!


Like in a 172, notice the way the nose comes down with flaps?



When you lower the flaps, you change the angle of incidence. With a fuselage
that remained level during the change, you would have increased the AoA.

True, but we are more concerned with maintaining a given airspeed rather than
a level floor...
