    Increased air traffic coupled with the proliferation of sophisticated avionics can be expected to stimulate increased demand for air traffic control (ATC) services over the next few decades. New challenges for the design of communication, surveillance, and navigation subsystems is an anticipated consequence. Since it is unlikely that significantly larger frequency bands will become available, it w... View full abstract»

    Early attempts to provide a semblance of air traffic control were based on simple "rules of the road" resulting from the European sponsored International Convention for Air Navigation (1919). The United States formulated its first regulations relating to air traffic following the passage of the Air Commerce Act of 1926. By 1930, radio equipped airport traffic control towers were being established ... View full abstract»

    The ATC radar beacon system is a descendant, through an extended evolutionary development, of military identification friend or foe (IFF) systems begun during World War II. It is today's primary source of surveillance data for air traffic control and performs this function with a high degree of effectiveness. A number of programs are underway to correct its current deficiencies. Looking to the fut... View full abstract»

    A measure of discipline must be imposed on the groundbased interrogator complex if a new discrete-address beacon system is to be compatible when introduced into the present air traffic control system. It is postulated that this discipline, if imposed in a certain manner, will provide a surveillance system that will provide several additional benefits and services to the aircraft operator at minimu...

    Computers, and digital techniques in general, have become pervasive in the technology of air traffic control (ATC). So much so that it is difficult to discover an area, application, or function in which automation is not involved, if only at the conceptual level. Rather than describing a single role for the computer, this paper examines some typical uses of computers in relation to the various fun... View full abstract»
