other aspects to consider wrt to swept wing aeroplanes are dihedral effect in terms of both stability and stall characterisics: the plan form effect of aerofoil section [that make up the total wing--where some sections may be of a differing airfoil design] the low lift slope curves of those sections, the higher angles of attack required to produce lift at low speeds as well higher angles of stall, the effect of other airplane--- stuctures--- fuselage, canard, tailplane position, only by assuming an swept elliptical planform are elliptical distrubution, dihedral efect washout and twist---this is why even with some basic equations for the characteristics of these sections bboth wind tunnel testing and FLIGHT TESTING must be done,...because even the geometry of the tunnel affects the actual characteriscs experience in flight; and lastly it depends on whether you mean wing section stall or 'airplane' stall

a good simple reference on high spped flight is found in H.H hurt's 'aerodynamics for naval aviators as well careful reading of some of Davies text reveals some more,...
