The FAA puts forward a lot of aerodynamic literature that is either oversimplified or flat-out incorrect. Just reference the ongoing battle to teach Newtonian principles in initial aerodynamic theory courses in addition to the FAA-sanctioned over-application of Bernoulli's Principle. Long story short, starting in the 1950's, a lot of these complicated principles were dumbed down to "our level" on the basis that we're pilots, not mathematicians, and we don't need to (or simply can't) understand the full story. When you go full Math Nerd and really get into the physics in play, you find yourself needing to unlearn a lot of The Sacred Truths as taught in ground school.
pilots ain't that smart;..... the USA invented it all and the whole world follows the Avigation Act of 1926 wheter or not they think so
nobody knows more about this stuff than the US government
a.....Newton's law ---wing pushes air down; air pushes wing up
b. the aerodynamic forces and moments can be computed from Bernoulii's relation F = MA ,...no more
