ABSTRACT
With the increase in air traffic, better management and organization of air traffic systems is crucial to improving flight safety standards and maintaining airspace capacity. This emphasizes the need for ad hoc descriptions of more complex and flexible aircraft trajectories, allowing high traffic densities and limiting the environmental impact. The approach involves the generation of a smooth 4D path from preexisting control points by joining several Bezier curves while maintaining G 2 continuity at the joints. Moreover, as the Euclidian distance between control points and the proposed trajectory is controlled by an optimal reshaping of the trajectory, the trade-off between the curvature-speed-load factor of the trajectory is considered. The generated trajectories are intended to be a complement to regular flight plans, thereby helping to resolve air traffic conflicts and enhance air capacity by better timing. MAT- LAB simulations corroborate the feasibility of the approach, indicating promising results when a distance range is defined for the reshaping algorithm.
