. Operations began in February 1946 under quadripartite flight rules Paragraph 4. Paragraph 4 of the rules begins: "The Berlin Air Safety Centre has been established in the Allied Control Authority Building with the object of ensuring safety of flights for all aircraft in the Berlin area. BASC regulates all flying in the Berlin control zone and also in the corridors extending from Berlin to the boundaries of adjacent control zones." Berlin_Air_Safety_Center_DF-SN-83-08062

The BASC was one of two four-power organizations to continue functioning following the onset of the Cold War, the other being Spandau Prison, which ceased operations following the death of Rudolf Hess on 17 August 1987. The BASC continued to ensure safety of flight, for 24 hours a day, with the three western powers being represented by a chief controller, along with a deputy and general duty controller; all were Air Force officers. The Soviets, in attempt to mitigate being out numbered, had both a controller and interpreter on duty until its closing on 31 December 1990, following the lapse of Allied responsibilities in Berlin.

The BASC coordinated air traffic in and out of Berlin and was responsible for air safety in the three corridors established in 1946 as well as in the Berlin control zone, the airspace within a radius of a pillar located in the cellar of the Allied Control Authority building. Each of the three corridors were wide and linked Berlin with the Western Zones of Occupation of Germany (later

). The three corridors were usually open, without restriction, only to the Four Power nations: United Kingdom, United States, France and USSR – other nations wishing to use the corridors had first to request and obtain permission from the BASC. Requests to use the southern corridor were handled by the US desk, the centre corridor by the French desk, and the northern corridor by the UK desk. The requests were then handed to the USSR desk for coordination, with Soviet air defense authorities, and in turn would be stamped in one of three ways: ''permission granted, safety of flight guaranteed''; ''permission granted, safety of flight not guaranteed''; or ''permission denied''.
