Content: When hovering, the wake turbulence surrounds the helo. When in forward flight, the wake turbulence trails behind the helicopter just like it does an airplane. It should be noted that wake turbulence is not the result of the airplane’s powerplant. Jets produce a powerful jet blast that is very hazardous to nearby aircraft on the ground. Even at low power, jet blast can topple light training aircraft. The prop wash from propeller-driven airplanes can also cause damage. But this turbulence is short-lived and remains close to the aircraft, generally much closer than anyone would ever operate to another plane in flight. The hazard for the following aircraft lies in the spiral vortex of the wake turbulence. If a plane unknowingly enters the vortex, it will induce a much stronger roll than the airplane’s flight controls can correct. A smaller plane that enters the wake turbulence of a larger aircraft is likely to wind up flying upside down!
