Wake vortices were investigated to see whether and under which meteorological conditions landing aircraft could be endangered by wake vortices generated by leading large transport aircraft on a parallel glide path. The crosswind shows an evident influence on the horizontal motion of a vortex. But its velocity during 56 pct of the time of the main air traffic is so slow that a vortex cannot reach the parallel glide path with dangerous intensity due to its limited life-span. Within the remaining time, the danger to a following aircraft depends very strongly on the meteorological conditions of the vicinity.
