How Are Airways Controlled?

Answer Question

1 Answer - Sort by: Date | Rating

    Airways are the bands of airspace 16 kilometres wide, along which commercial aircraft are separated from each other by Air Traffic Controllers on ground.

    On busy airways such as those in Western Europe, this separation is achieved using radar. The radar gives the controller a picture of all the aircrafts in that area. With newer systems, the flight number and altitude of the aircraft are also displayed. The controller will be in communication with his military counterpart to arrange clearance for military aircrafts to cross the civilian airways.

    The turning points of the airways, where a change of course is required by the aircraft, are marked by radio beacons. The pilot selects the frequency of the beacon and may select the course he wishes to fly to the beacon. His flight deck instruments then tell him whether he is right or left of the required course.

    There is another type of beacon where the pilot simply has a needle on his instrument panel which points to the beacon. This type is called 'Non Directional Beacon' or NDB.
