GM1 ATS.TR.220 Application of wake turbulence separation ED Decision 2020/008/R WAKE TURBULENCE EFFECTS INDUCED BY HELICOPTERS (a)       Helicopters should be kept well clear of light aircraft when hovering or while air-taxiing. (b)       Helicopters produce vortices when in flight and there is some evidence that, per kilogramme of gross mass, their vortices are more intense than those of fixed-wing aircraft. When hovering in ground effect or air taxiing, helicopters generate downwash producing high-velocity outwash vortices to a distance approximately three times the diameter of the rotor.
