Optimizing Tomorrows ATM Using 4D-Trajectory-Based Operations

Kurzfassung

Performing the paradigm shift to 4D-Trajectory-Based Operations will involve several procedural improvements. High planning predictability allows better usage of airspace and dropping some of today’s constraining factors. Efficiency improves by flying aircraft specific optimized procedures. By usage of sophisticated models and planning algorithms, total system’s performance will come close to global optimum. This paper describes a new and powerful way of modeling 4D airspace incorporating traffic, weather, restricted areas and any other objects existing/moving in 4D airspace. The model represents these objects in a way allowing very fast conflict detection and resolution in order to find a feasible and efficient global solution.
