For pairs of aircraft whose 2-D or 3-D flight routes 402, 404 violate a proximity test, the parts of their flight routes that breach a horizontal separation threshold 308 are identified as conflict paths 406, 408. Aircraft conflicts are then identified for portions of the trajectories corresponding to the conflict paths (Figs.6-7). Thus portions of the trajectories corresponding to positions outside the conflict paths may be eliminated from the conflict detection, increasing computational efficiency. Time separation and altitude separation of pairs of aircraft that have not flown past their conflict paths may be used to predict loss of separation. Graphical warning indications for pairs of hazarding aircraft may show time separation (1616, Fig.16) and rate of change thereof. Conflict paths may be pre-determined, stored and used later for conflict detection in an air traffic control system.
