How does an aeroplane fly? Is it Bernouli, or angle of attack, or both?

If you go for a pilot licence if you do not pick bernouli you are marked wrong, but angle of attack is an effect that causes downwash for crop dusters, and also explains why planes can fly upside down.

We made a video to explain how a wing works, which provides a clear explanation, we hope.

Aerobatic planes are designed with a symmetrical wing cross-section, and near-zero angle of incidence. They gain most of their lift by adjusting the angle of attack. This allows the handling characteristics to be consistent when flying inverted.

Aerobatic planes can also fly with the wings vertical, by using the body of the plane to provide lift. I imagine this would require a significant angle of attack.

But these maneuvers are not recommended for general aviation or commercial flights.

See, for example:  (other brands are also available)
