Concept and Laboratory Analysis of Trajectory-Based Automation for Separation Assurance

This paper presents a four-dimensional (4D) trajectory analysis automation method for collision avoidance decision support in the National Airspace System (NAS). Authors use the NASA-developed Center/TRACON Automation System (CTAS) as the basis of their automation method and human-in-the-loop laboratory simulations. In the simulations, air traffic controllers generated manual conflict resolution trajectories. Data from the Fort Worth Center air traffic control (ATC) were used. It was found that, using the system, direct route aircraft could increase their flying time efficiency by about five percent. In a simulation run with twice the regular traffic at Ft. Worth, a single controller was able to maintain aircraft separation in all but one instance, although it is noted that the post-simulation analysis attributed the error to the controller and not the assistance program.
