Without getting technical; The pressure differential is caused by the shape of the wing. The bottom is essentially flat while the upper part has a curve to it. As air passes over it, it must travel further past the curve but it still meets up with the air that went under the flat part of the wing at the same time. Since it covers a longer distance in the same time it has to move faster. That speed lowers the air pressure. If you want to see that in action, hold a piece of paper out flat and blow air above it, you will see it rise.
In flight, the air pressure above the wing is less than that below it.
Air pressure above the wing is relatively smaller than that below the wing because that is what generates the lift the plane needs to fly into the sky, but if it is the other way round, the lift won't be generated and the plane will remain on ground.
The pressure above the wing be Save comes less than the pressure below the wing.
The air above an airplane wing in flight is at lower pressure than the air below the wing. Hope this helps.
Low pressure is created over the top of the wing while higher pressure is below the wing which generates lift.
velocity and the difference in pressure above and below the wings
above - sky as below - ground above - airplane as below - subway
From Bernoulli's theorem this results in the air above the wing to form a low pressure compared to the air beneath the wing. High pressure moves to low pressure so you get lift
It's called "lift" and is the difference in air pressure between above and below the wing.
Faster-moving air across the top of the wing lowers the pressure there. For a plane to ascend, the pressure must be sufficiently lower on top of the wing, and it will be forced upward by the greater pressure below the wing.
Winglift.Lift is pressure on the wing due differential air pressure below and above wing. This difference results from the difference in curvature of the wing top and bottom..
