4D-trajectory based operations is one of the big enabler for future efficient and environmentally friendly air traffic management. Every aircraft is assumed to fly along a predicted 4D path that can be calculated from gate to gate pre-flight. 4D trajectories are optimized individually for aircraft models, routes, weather conditions and airline preferences. However, individual calculation of trajectories does not ensure conflict-freeness, neither between aircraft nor with environmental constraints like severe weather zones or restricted areas. The presentation is about an efficient algorithm detecting conflicts for large traffic scenarios. Basic idea is an N-dimensional bisection of airspace allowing a significant reduction of complexity. Thus, potential conflicts are identified very fast. A slower high precision conflict check is performed on potential conflicts only. That way, conflicts of one 4D-trajectory can be detected in a European traffic sample holding more than 30k flights in ~10ms on standard PC hardware. Fast detection times are also predestined for trial-and-error conflict resolution. Different conflict resolution methods are presented, taking into account the major key performance areas in air traffic management, e.g., safety, efficiency, and predictability.
