TEST AND EVALUATION OF THE CONFLICT ALERT FUNCTION (HIGH ALTITUDE) WITH THE NAS ENROUTE A3D2.1 SYSTEM

This report deals with aircraft trackings for separation violations. It describes the operational evaluation of a collision alert function interfaced with the National Airspace System (NAS) Enroute A3d2.1 system. Tests were conducted in a beacon only high-altitude environment with simulated digital target data. Tests were designed to evaluate the performance of the conflict alert function with respect to detection capability and adequacy of warning provided. Tests were conducted in two modes of operation: a 'conflict alert warning only' mode in which controllers took no action to resolve potential conflicts until an actual alert was generated by the conflict alert algorithm, and a 'conflict alert backup' mode in which controllers performed all normal air traffic control duties and took immediate action to resolve potential conflicts without waiting for an alert to be generated.
