The purpose of this project was to provide further evaluation and refinement of the Automatic Traffic Advisory and Resolution Service ATARS concept. The tests were conducted at the National Aviation Facilities Experimental Center NAFEC at Atlantic City, New Jersey, using the Air Traffic Control Simulation Facility ATCSF. Test results indicated that ATARS had no significant impact on the controllers or control procedures in a Philadelphia Terminal Control Area TCA environment. Outside the immediate TCA, where the majority of encounters occurred, the factors contributing to the generation of alarms were, in general, satellite operations and the use of Visual Flight Rules VFR separation criteria. The incidence of positive resolution advisories was low, averaging only 0.5 encounters per hour. Recommendations are to reduce the size of the ATARS desensitization zone at the Philadelphia main airport to approximately 2.0 nautical miles nmi from runway thresholds, to incorporate a convergencedivergence detection filter into the ATARS algorithm, and to investigate the possibility of reducing tracker lag by improving turn and level off detection.
