Interim Developments in Air Traffic Control 620359
Interim developments which bridge the gap in ATC system improvements between immediate programs and the longer range objectives of the FAA's National Airspace utilization System Design are presented. The system design specifies that pilots and controllers shall have independent means of position determination.
The national system of VORTAC/ILS aids which provide the position information used by pilots for this purpose is described, including an outline of the Acency's improvement plans in the next five years in this and the related field of air/ground communications.
Radar and radar beacon are the independent source of aircraft position information for use by controllers. FAA plans for implementation of improved radar beacon interrogators, transponders, decoders, and procedures are described. The relationship of these developments with concurrent improvements being made at ATC display and processing equipments is noted.
