Generating optimal aircraft trajectories with respect to weather conditions

Abstract : Two major projects have been initiated to improve air traffic management by enabling 4D trajectory planning, whereby the aircraft plan their trajectory both in position and in time. In this paper, we are interested in a Free Flight variant of the concept, whereby airspace users are allowed maximum freedom when selecting routes: aircraft are no longer restricted to fly along airways; rather, they are allowed to fly along optimal routes, from origin to destination, following optimal altitudes, using favourable winds and avoiding hazards. Such optimal routes are good for the environment, for the airlines, and for passengers. The goal of our research is to generate trajectories which minimize congestion and travel time of each aircraft in a way that is fair and efficient. We first optimize the route of a single aircraft relying on an algorithm called Ordered Upwind. And then, with a multi-agent system, we modify trajectories in order to minimize the congestion and to stay as close as possible to the optimal trajectories.
