An Hp-adaptative pseudospectral method for conflict resolution in converging air traffic

Abstract

This paper presents a conflict resolution method in converging air traffic based on an hp-adaptative pseudospectral method. The technique generates conflict free trajectories in scenarios with multiple aircraft. This method computes an optimal solution numerically. It assigns a speed profile to each aircraft sequencing the order of arrival to the TMA entry point such that the separation between them is greater than a minimum safety distance and the total deviation from the initial trajectories is minimized. The paper also presents simulations in converging scenarios by considering unlocked and locked aircraft. © 2015 Springer International Publishing.
