I like to think I have a decent understanding of how an airfoil works. Not enough for being an aerodynamics engineer or something, but enough for being a pilot.

@TannerSwett Someone asked a question about velocity around the airfoil. It's not the same as what you're asking here, but maybe the answers will give us some insight, because I don't think assumption that "the horizonatal velocity of the air flow is constant throughout the chord" is correct.
He also brings up something that has been puzzling me. At the leading edge, the air is being accelerated, which Bernoulli shows that the pressure will be lower, resulting in upward force. But by the "flow turning" explanation of lift favored by NASA seems like it doesn't quite work. At that point on the wing the flow turning is in an upward direction, which should result in a downward force on the front of the wing. Something seems amiss.
