Evaluation of a radically revised air traffic management interface

By taking into account the capabilities of modern computer-based control systems, and modern knowledge of human cognitive capabilities and limitations, it is possible to produce an 'en route' air traffic management system which has a considerably greater capacity than the existing system - although this requires considerable changes in the way that control is exercised. The model described included checks for unintentionally unsolved conflicts and incorrect departures, improved symbology for errors in departures and a provision for a rapid switch between the two aircraft in a conflict. It also included more detailed recording of simulation events, and more precise calculations of departure times. The time, place and flight level for exit for each aircraft were planned as they were generated, and aircraft were required to leave at that spacetime point, unless this would involve a conflict.
