Wake turbulence is one of the most common flight disturbances. Most pilots experience it on a regular basis. In short, wake turbulence is the result of wake vortices that are created whenever an airfoil produces lift. Lift results from a pressure differential at the wing surfaces, with the lowest pressure occurring above the wings and the highest pressure occurring beneath them.
