Fewer Airport Vortices
The German Aerospace Center has developed panels to be set up alongside runways for minimising the air vortices caused by aircraft. Drawn out vortices in the wake of aircraft can throw smaller aeroplanes off course and therefore warrant a safety clearance of currently about 10 km. Since the new ground panels cause these long-lived air vortices to dissolve more quickly, aeroplanes could in future land in closer succession. The more efficient utilisation of runways would, for instance, eliminate the need for their expansion.
