Closed-Form Pairwise Aircraft Conflict Resolution with First-Order Uncertainty Propagation

This paper presents a closed-form framework for detecting and resolving predicted losses of horizontal separation between two level aircraft. In the relative-velocity plane, the method derives the time and distance of closest approach, the first loss-of-separation time, the compl...

Complete Analytical Solutions for Pairwise Aircraft Conflict Resolution and First-Order Error-Propagation Assessment of Solution Uncertainty

Air traffic controller workload for separation assurance grows with traffic density, moti- vating automation of conflict detection and resolution (CD&R). This paper develops a com- plete, case-exhaustive closed-form treatment of the resolution of predicted losses of horizontal se...
