4-Dimensional Trajectory negotiation and validation system for the next generation air traffic management

As part of the ENDEAVOUR project (Evolutionary Network-Centric Technologies for Four Dimensional Trajectory (4DT) Based Operations in Europe: ATM and Avionics Systems for Intent Validation, Real-Time Optimisation and Uncertainty-Resilient Operations), a novel 4DT Planning, Negotiation and Validation (4-PNV) system was developed for integration into the next generation Communications, Navigation and Surveillance/Air Traffic Management (CNS/ATM) environment. The 4-PNV system provides 4DT negotiation and validation capabilities for the Next Generation ATM, in combination with the Next Generation of Flight Management Systems (NG-FMS) and Next Generation Air-to-ground Data-Link (NG-ADL) that are also being developed. The NGFMS generates globally optimal trajectories based on environmental and operational weightings, meeting the combined objectives of the Single European Sky ATM Research (SESAR) and Clean Sky Joint Technology Initiative for Aeronautics and Air Transport programmes. The 4-PNV system receives multiple options of 4DT intents from each aircraft equipped with NG-FMS, and validates them through real-time negotiation, resolving traffic conflicts, thus establishing optimal and safe trajectory solutions for each aircraft.
