The lift produced in a Aero Plane works on Bernoullie's principle. The key to lift generation is the shape of the cross-section of the wing. If you look at the cross-section of the wing, you can see that the curvature is more on the upper part. That means the air passing through the wings, after getting separated from the nose of the wing, moves faster on the top surface and slower on the bottom surface.
According to the Bernoullie's Theorem, faster moving air on the top surface causes pressure to decline there, while the pressure is higher at the lower surface. This differencial pressure causes a force in upward direction,which is proportional to the surface area of the wing, on the upper direction and the plane lifts up.
This is the simplest explanation of the lift generation for an aircraft.

the shape of an aircraft wing is designed in such a way that the velocity of the air above the wing is greater than that below it.a region if low pressure is terefore created above the wing and so the aircraft experiences an upward force called lift
you can easily verify it by applying bernoulli equation
