After continually hearing the half-explained answer to how lift is achieved over an airplane wing, we decided to tell the whole story. It is well known that lift occurs when the pressure on the bottom of the wind is greater than the pressure on the top, and this pressure difference over comes the weight of the aircraft and obtains lift. This pressure difference is often explained as a Bernoulli problem where the airfoil causes the velocity at the top to be faster than the velocity on the bottom and that is
