Two realtime simulation experiments were conducted at the National Aviation Facilities Experimental Center NAFEC for the purpose of investigating the interface between the Air Traffic Control ATC system and a proposed Airborne Collision Avoidance System ACAS. Based on results of those experiments, it was concluded that 1 Some means of desensitizing the ACAS in the final approach sequencing and spacing zone of busy terminal areas was mandatory, and 2 The concentration of ATCACAS interaction would probably vary from site to site. In lieu of further realtime simulation, track history data were recovered from the Washington, Chicago, Los Angeles, and Miami ARTS III facilities. After intermediate processing, the digital representation of the traffic flows were inspected by a software model of the ACAS. Results were reduced in the form of alarm rates, before and after desensitization. Results of the analysis confirmed the conclusion that some form of desensitization would be required.
