But that seems a bit too simple: they're implying that there's a possible contradiction here. I suspect that the answer is in Bernoulli's or Euler's equations, which I've heard are linked to why planes fly. But that's well ahead in my notes and I don't understand any of that ...

Why does the air flow faster over the top of an airfoil?

WebDue to the curvature of the wing, the higher velocities and acceleration over the top ofthe wing requires a pressure above the wing lower than the ambient pressure.
