Abstract:The Federal Aviation Administration (FAA) is currently engaged in the development of an Active Beacon Collision Avoidance System (BCAS) as a part of its Aircraft Separation Assurance (ASA) Program. Designed to operate in both controlled and noncontrolled airspace, BCAS performs its separation function through the active interrogation of the Air Traffic Control Radar Beacon System (ATCRBS) and/or the Discrete Address Beacon System (DABS) transponders of other aircraft. Operating in this fashion, BCAS is primarily an airborne system. Under certain situations, however, BCAS uses a ground-based 1030-megahertz (MHz) transmitter/receiver known as the Radar Beacon Transponder (RBX). The purpose of the RBX is twofold. First, it provides a means for desensitizing (adapting) the BCAS threat logic to the reduced aircraft separations that arise in terminal areas. This has the effect of reducing the probability of unwarranted threat declarations by BCAS. Secondly, the RBX provides a data channel whereby BCAS evasive maneuvers displayed to the pilot can be relayed to the appropriate air traffic control (ATC) facility. The ATC facility would be that terminal facility in whose airspace the BCAS is flying.
