An adapted Fast Marching Tree for contrails mitigation: A short-and long-range flight study
Résumé
This paper addresses the problem of finding a trajectory for an aircraft minimizing its total environmental impact. In particular, CO2 and contrails are considered. The Fast Marching Tree method is known to be efficient to find trajectories avoiding obstacles. This method is adapted to the case of soft obstacles, here areas favorable to contrails. This study is done in 2D and for the cruise phase of airliners. Two case studies on short-and long-haul flights are presented. The given results show trajectories minimizing the overall impact according to the given metric by trading off between CO2 and contrails. Moreover, they are obtained with a low computation time allowing one to consider extensions. Finally, an improvement concerning the sampling is proposed, reducing the computation time and cost.
