ATARS/ATC SIMULATION TESTS WITH SITE-ADAPTATION LOGIC

The objective of this project was to assess the effectiveness of proposed Automatic Traffic Advisory and Resolution Service (ATARS) site-adapted logic designed to reduce unnecessary alarms in a terminal air traffic control environment. 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 the site-adapted logic reduced the numerous unnecessary alarms experienced in previous simulation tests. In fact, no ATARS alarms were generated in any of the tests involving instrument flight rules (IFR) separation procedures. Under IFR and/visual flight rules (VFR) separation rules, a total of seven ATARS controller alerts was issued over four 1-hour data runs. One aircraft received a positive vertical command, and four received negative horizontal commands; the remaining aircraft received flashing proximity warning indicators (FPWI's). The majority of the eight controllers participating in these tests favored ATARS use and indicated that ATARS with site-adapted logic did not impact control procedures. Recommendations are made for further improvement in ATARS desensitization in the terminal ATC area, for additional studies to improve tracker performance and ATARS performance under reduced VFR ATC separation criteria, and for additional tests to evaluate ATARS performance in a terminal environment with uncontrolled aircraft flying in proximity to controlled aircraft.
