Thank you for sharing a very instructive video. The graphics add to the clarity of the subject. Yours is the best I have seen so far.

[@fredbloggo]

Really good and bought together a few different concepts for me

[@marcozbo]

Your lessons are really good. If I have to nitpick, that background with a bluish curved shape may distract sometimes... it looks like air flow! 🙂

[@SailZing]

Thanks for the feedback! If YT would allow updating videos without losing history, we could change it. Will definitely keep that in mind for new videos though.

Gonna jump in here after the airplane wing analogy. Changing the attitude of the wing to airflow does change the AoA, but it does not control the climb or dive behaviour. That is controlled with the throttle. The old model Bernoulli model of pressure difference has also been - not entirely- discredited but still in vogue because it is easier to understand than Circulation Theory. Which is how lift actually works on an airfoil, but nobody wants to do the math, or at least very few are capable of the calculus. You don't really need to work the numbers, the telltales are doing that.
