The evolution of present day Air Traffic Management ATM towards an integrated Air Traffic Management will lead to the introduction of computer based planning systems on the ground side, which communicate with advanced Flight Management Systems onboard the aircraft via automatic data link. An experimental Flight Management System EFMS is under development in the frame of the PHARE program for research into future ATM concepts. This EFMS will have the capability to predict a 4-dimensional trajectory according to a set of constraints given by an ATC planning computer on the ground. It will negotiate this trajectory with ATC via data link and will generate appropriate guidance commands for the autopilotautothrottle system to steer the aircraft along this trajectory. This paper describes briefly the functionality of the EFMS and then concentrates on the planning strategy for the generation of a trajectory from the departure to the destination airport which meets the defined constraint attributes.
