The turbulence caused by the passing of an aircraft through a body of air. Greater horizontal separation must be provided behind wide-body aircraft approaching or departing from airports because of the greater wake turbulence they create.
Turbulent air behind an aircraft caused by any of the following: (a) wing-tip vortices;(b) rotor-tip vortices;(c) jet-engine thrust stream or jet blast;(d) rotor downwash;(e) prop wash. Fr: turbulence de sillage
turbulence created by an aircraft's passage through the air.
Turbulent air condition caused by small, tornado-like horizontal whirlwinds training an aircraft's wingtips (wingtip vortices). Wake turbulence associated with larger aircraft flying at slow speeds (as on take-off or landing approach) is the most severe and can cause loss of control for smaller aircraft following close behind. Controllers use defined separation standards to avoid the problem for take-off, landing, approach and departure operations.
Every aircraft in flight generates a wake of turbulent air. The disturbance created by the wake is caused by a pair of counter rotating vortices trailing from the wingtips of the aircraft. The vortices from large aircraft pose problems to encountering aircraft. and if encountered at close range, can damage aircraft components and equipment and cause deaths or injuries.
wingtip vortices generated behind a wing producing lift. Behind a large heavy aircraft they can be powerful enough to roll or even break up a smaller aircraft.
A disruption of airflow caused by the passage of a body through the air. In aviation, wake turbulence has been known to cause upset of one aircraft following another. The Federal Aviation Administration has issued regulations requiring aircraft to take off, land, and fly minimum distances behind other aircraft. These distances vary by aircraft type.
Wake turbulence is turbulence that forms behind an aircraft as it passes through the air. This turbulence includes various components, the most important of which are wingtip vortices and jetwash. Jetwash refers simply to the rapidly moving air expelled from a jet engine; it is extremely turbulent, but of short duration.
