Conflict Detection and Resolution for Air Traffic Control

Dr. Heinz Erzberger
NASA Ames Research Center


The basis for detecting air traffic conflicts is a technique for synthesizing four-dimensional trajectories that can accurately predict the position of aircraft 20-30 minutes into the future. An equally important ingredient of conflict detection involves modeling the uncertainty inherent in the trajectory prediction process. Recently a new technique has been derived for generating conflict probability as a function of prediction error and conflict encounter geometry. These techniques have been incorporated in an operational system that provides conflict detection and resolution advisories for air traffic controllers.
