I agree - the subject is sufficiently complicated without introducing Daniel Bernoulli! The above is correct in the case of the x-axis of the fuselage being coincident with that of the wing chord but Vessbot's was wondering why a wing AoA (disregarding wash-out) necessarily has to be related to the angle of incidence of the fuselage. The answer is, of course, that it doesn't.
