Green Route Optimisation for Low Altitude Flying Aircrafts

Flight path, aircraft altitude, speed and power settings over populated areas directly affect noise and emission cumulative exposure. In this study these factors are analysed in order to devise a strategy for minimizing the environmental impact of low-altitude flying aircrafts, approaching/leaving airports over congested areas or performing surveillance missions. Two approaches are proposed, the first is based on a geometric algorithm and the second on operations research techniques. The algorithms are implemented on realistic scenarios and the obtained results are compared.
