Generation of conflict resolution manoeuvres for air traffic management

ations of the controllers. Recent trends in air traffic W e explore the use of distributed on-line motion planning algorithms for multiple mobile agents, in A i r Traflc Management Systems (ATMS). The work is motivated by current trends in ATMS to move towards decentralized air trafic management, in which the aircraft operate in “free flight” mode instead of following prespecijied “sky freeways”. Conflict resolution strategies are an integral part of the free flight setting. The purpose of this paper is to obtain a set of maneuvers to cover all possible conflict scenarios involving multiple agents. A distributed motion planning algorithm based on potential and vortex fields is used. While the algorithm is not always guaranteed to generate flyable trajectories, the obtained trajectories can serve as qualitative prototypes for coordination maneuvers between multiple aircraft. The actual maneuvers are generated b y approximating these prototypes with trajectories made up of straight lines and are further verified usang hybrid verification techniques.
