I've always found venturi and Bernoulli principles to be adequate for pilots although they may not satisfy the geeks. I learned my aerodynamics in the RAF from Kermode (?) and I never broke an aeroplane because of my ignorance. It was also a satisfactory expanation for the many hundreds of glider and jet pilots I have subsequently taught to fly.
Everyone must know that an aerofoil fails to produce enough lift when the angle of attack becomes too high for the bernoullis to hang on and they roll off the trailing edge, often causing a buffeting through the airframe as they roll and their lift arrows thrash the wing surface.
