Harmful trailing vortices downstream of an aircraft wing are at least partly dissipated by a respective counteracting vortex for each trailing vortex at each wing. An auxiliary counteracting vortex generating flap, preferably in the form of at least part of a delta wing, is journaled to the respective wing in the area of the outer end of a landing flap. The counteracting vortex is imposed on the respective trailing vortex, whereby the trailing vortex is caused to vibrate. The vibration dissipates the trailing vortex at least partially.
