Trajectory based ground movements and their coordination with departure management

Today no detailed ground trajectories exist; although trajectory based ground operations would improve the runway sequence optimization by more accurate taxi times. The aim of this study was to extend the time-based trajectory management to the ground and link it with departure management. A specific futuristic mean to achieve time-based trajectories on ground is by precisely controlling the speed of aircrafts. A concept for a surface management system is introduced, which supports air traffic controllers in this task. The interactions between this advanced surface management system and departure management are studied by building and extending surface and departure management research prototypes. Preliminary results from a workshop with air traffic controllers indicate that our concept is promising.
