English to Swedish Tech/Engineering Aerospace / Aviation / Space Navigator f�r bilar

clearway an area beyond the takeoff runway that is under the control of airport authorities where terrain or fixed obstacles may not extend above specified limits (these areas may be required for turbine-powered operations and the size and upward slope of the clearway will differ depending on when the aircraft was certified)

Det här handlar om en navigator för bilar, men ordet clearway har ingen vidare förklaring och jag hittade ovanstående på Googles.
