      7:37 The foil is a wonderful discovery! From a physics perspective, it's not enough to say that pressure decreases because of velocity :) what makes the velocity increase on the upper side of the foil it's really the pressure decrease! Because of the shape of the wing, right after the highest point of the curve of the wing, the pressure will be lower, because there will be less air in there. And why? Because it just got out of its way! The air had to go around the foil! So with less air in there, the pressure will be lower indeed! The increase in air velocity, in this particular flow, is not the cause, but a consequence! In engineering we really like to manipulate the speed of air to control pressure, but in this beautiful invention that is the foil, it's actually the opposite! The wing foil is marvellous and maybe because in engineering it's more common to use Bernoulli's. equation the other way around, it is very very common to explain this the other way around! Which is fine really, because the practical result is the same: lift, which is what makes us happy. When I took my physics MSc a few years ago, I did a bit of research in fluid dynamics for aircraft. This took me back :) my love for aviation actually comes from this concepts. So subtle, yet so powerful that anyone can now cover the world in two or three flights.
      Amazing content!! This is the perfect setup for student pilot theory content creation on youtube. Congratulations 👏🏼

    I hope you guys are able to push these out more frequently. This is a good review for me. I'm 60% done with the ground school

    Thank you for the great content! I have one question about Static Stability and DS, when we talk SS and DS are more likely about airplane longitudinal stability, right? In video 26 minutes the explanation of positive and natural and negative in turn and how the airplane reacts to control input is more like the effect of dihedral and over banking tendency isn't it?

    • @PilotInstituteAirplanes

      Stability is usually discussed around pitch. With that said, dihedral is just a way to create positive stability along the longitudinal axis.

    The graph at 12:29 is difficult to understand. The normal expectation for a graph in any other context is that the origin (x and y axes cross point) is 0,0... but either your line is wrong, or this is not the origin on this graph, because a plane traveling at zero velocity (through the air) produces zero lift and therefore zero induced drag. I suspect that you intend the origin to be Vs,0? If so that's probably worth mentioning since you just got done explaining that it was a proportion of lift. It also clarifies why the blue line doesn't start at the origin.
