WebThe vortex circulation is outward, upward and around the wing tips when viewed from either ahead or behind the aircraft. Tests with large aircraft have shown that the vortices remain spaced a bit less than a wingspan apart, drifting with the wind, at altitudes greater than a wingspan from the ground. WebWake turbulence is a type of clear-air turbulence. In the case of wake turbulence created by the wings of a heavy aircraft, the rotating vortex-pair lingers for a significant amount of … WebFeb 2, 2024 · Have you ever heard "caution wake turbulence" on the radio?
