How do wings generate lift?

This is clearly wrong because stunt planes and military jets can fly inverted.

They push air downwards, generating lift

It isn't bullshit, in stable flight, the air always goes faster over the upper part of the wing (relative to the ground). You can use Bernouli's principle to explain the lift.

>the wing will have an angle of attack (meaning it's pointed slightly upward, about 1-15 degrees)
Wrong, this only applies for symmetrical airfoils. The angle of attack (=angle between moving air and chord line) doesn't need to be positive. Most wings generate lift at negative angles of attack.

I STILL DON'T FUCKING GET IT
>WHY
DOES MOVING AIR HAVE LOWER PRESSURE REEEEE
Why was I born a brainlet.

only one of these statements are true

Not the guy you're replying to, but stunt planes have a more symmetrical wing profile, and rely on angle of attack to generate when upside down - that is, the nose is tilted upwards relative to the direction of movement.

Of course, if you tilt up too far, you get flow separation on the trailing edge of the airfoil, which leads to your stall condition.

Yeah I thought both the angle of attack and the shape created lift. The shape is not necessary but it's useful, like having the edges of the wing pointing upward.

conservation of energy senpai, or in this case the Bernoulli principle

The math makes sense, but I don't get why particles moving over a flat surface will generate less pressure than if they were still.

There is a drop in pressure on a cambered airfoil however it is not enough to provide all of the lift that is required for flight. For a small aircraft such as a Cessna 172 to fly just using just the Bernouli principle it would need to be moving at around 400 knots (~200 m/s). The wings fall off once you reach 200 knots.
