This REPORT is part of a project that has received funding from the SESAR Joint Undertaking under grant agreement No 699247 under European Union’s Horizon 2020 research and innovation programme.

This report is the deliverable D4.3 “System Validation Report” of the R-WAKE project, which contains a summary of the methodology and tests conducted to assess the confidence of the models used in the R-WAKE System as well as about the data generated by the system. Validation results indicate that the models used are congruent with the literature background and historical records available. The level of accuracy and confidence achieved in this project is considered valid for V0 maturity and even for higher levels of maturity. However, further validation against real wake vortex data measurements in en-route phase of flight will be needed in the future for further validation and refinement of the models and of the research results and conclusions. The R-WAKE project addresses the SESAR 2020 Exploratory Research work-programme topic ER-07-2015 - Separation Management and Separation Standards, within the area of Advanced Air Traffic Services (ATS). The R-WAKE project overall objective is to investigate the risks and hazards of potential wake vortex encounters in the en-route airspace, in current and futuristic operational scenarios, in order to assess potential enhancements for the Separation Standards and Separation Management methods in Europe.
