R-WAKE - Safety and robustness analysis

This report represents deliverable D5.2 Ed.2 'Safety and Robustness Analysis' of the R-WAKE projectand is part of WP5 (Simulation and Analysis) and has the objective to provide an evidence-basedproposal for either maintaining current separations, or adopting new potential separation schemes,that is, the R-WAKE Concept(s) to be further investigated. 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. Deliverable 5.2 'Safety and Robustness Analysis' 2nd Edition covers the preliminary identification of hazards in the scope defined by R-WAKE, followed by the identification of the impacted Safety Services. A notable advancement in the SRA is the refinement of the Severity Matrix with Upset Parameter Threshold (SMUP) with the integration of the ATC point of view. The initial, adapted FAA Severity Matrix contains also the ATC perspective now. A summary of the second Expert Panel is also detailed in this document, as well as the results of the ATC focus group conducted in Padova. Finally, the elaboration of a new AIM model paves the road to the initial development of Safety Criteria, also present in this deliverable.Preprin
