Wake turbulence is turbulence that forms behind an aircraft as it passes through the air. Wingtip vortices occur when a wing is generating
lift. Wake turbulence exists in the vortex flow behind the wing. The strength
of wingtip vortices is determined primarily by the weight and airspeed of the
aircraft.Wingtip vortices make up the primary and most dangerous component of
wake turbulence. This is the reason the separation criteria had to be written
out for A380.
