Question

What causes a flight to fly in air?

Answer 1

The air pressure above an aircraft wing is lower than that below the wing during flight.

Explanation:

The air pressure above an aircraft wing is lower than that below the wing during flight. The pressures on both sides of the wing exert forces on the wing. The higher pressure under the wing exerts more force than the lower pressure above the wing, causing a net force that pushes up, allowing the aircraft to fly. This is referred to as Bernoulli's principle.
