Airport Trivia : Control Tower (Airfield Control)
Control Tower (Airfield Control)
The building is located in such a way that the runway can be seen most clearly, and the top floor has a glass wall with a 360-degree view in all directions.
When there are multiple runways, the tower must be located at a high point in order to have a clear view of the runways. The height at Narita and Kansai airports is about 84 m, and at Haneda airport it is about 77 m. At airports on remote islands with short runways, for example, the control tower is only 25 to 30 meters high.
Inside the tower is a control console, which contains radio telephones, weather information, a clock, and a board for displaying operation tickets, as well as a light gun and binoculars.
At larger airports, an airport surface detection radar is installed to confirm the location of aircraft and vehicles at night or in bad weather.
Aerodrome control is the visual control of the airport and its surroundings. It is divided into three main areas: airfield control, which gives instructions and permission for takeoffs and landings; ground control, which controls aircraft and vehicles off the runways, including aprons and taxiways; and control approval transfer stations, which are located at large airports with high traffic volumes. This job involves communicating with the airway control and then approval (permission to route to destination and cruising altitude) to the aircraft.
