AIR TRAFFIC CONTROL/FULL BEACON COLLISION AVOIDANCE SYSTEM CHICAGO SIMULATION

The purpose of this project was to investigate Air Traffic Control/Full Beacon Collision Avoidance System (ATC/BCAS) interaction in a high-density terminal area (featuring parallel instrument landing system (ILS) approaches) and to provide data for a comparative study between BCAS and other aircraft collision avoidance systems. The tests were conducted using the Air Traffic Control Simulation Facility (ATCSF) at NAFEC during March and April 1978. Analysis of the results indicated that the presence of BCAS had no adverse impact on the controllers or control procedures because of a very low interaction rate. Controllers were generally indifferent to the use of the BCAS during the simulation. A significant number of controllers desired the displaying of negative commands. Throughout the simulation, BCAS issued a high number of vertical speed limit (VSL) alerts; however, most of these were advisory in nature, having no effect on the aircraft flightpath. Certain changes in the BCAS logic are identified which would significantly reduce the VSL alert rate in the terminal area without derogation of safety. Recommendations are made to investigate further densensitization techniques and further development of a multi-aircraft resolution logic, and to perform additional real-time simulation to assess the effect of profile descent procedures on BCAS alert rates.
