Why 2.5 deg lower than Flaps 3, and why would the alpha-max be only 0.5 deg above alpha-floor (14.5 deg) in the Flaps FULL case, instead of the apparent 2.5 deg margin with Flaps 3 (17.5 deg and 15 deg respectively)?
I seem to remember from aerodynamics classes that higher flap settings yield lower critical AoA (but of course higher CL values) - that could explain why Conf Full has lower alphamax than Conf3.
Then, there's higher slat deflection for Conf Full, which should increase the stall AoA, but maybe the flaps effect offsets the slat effect?
