WebThe flow rate difference across an airfoil produces a pressure gradient, resulting in lift. As angle of attack increases, flow separation will eventually occur, creating excess drag and resulting in stall. The wings on aircraft are very slightly tilted in order to produce lift during flight, and this tilt angle needs to be carefully chosen.
