Wake Turbulence

Wake turbulence is a function of an aircraft producing lift, resulting in the formation of two counter-rotating vortices trailing behind the aircraft. Every aircraft generates wake turbulence while in flight. Wake turbulence can be dangerous for following aircraft that may pass through it, especially if the turbulence was created by a larger or heavier plane. 

The process of wake turbulence separation is a precaution that can be applied to help protect trailing aircraft from experiencing the dangers of wake turbulence.

Pilots should always be aware of the possibility of a wake turbulence encounter when flying through the wake of another aircraft and adjust the flight path accordingly.
