ATM4E - Work Packages
WP1 develops a methodology for generating environmental change functions which are required to assess environmental impact assessment of ATM operations. Such ECFs establish a direct link between aircraft emission and environmental impact, i.e. linking emissions with climate impact, air quality, and perceived noise. This concept originates from the REACT4C project, where comprehensive climate-change functions were generated. Based on these change functions calculated by climate-chemistry modelling, ATM4E further develops the concept and simplifies the calculation of CCFs, by introducing algorithm based ECF that avoids complex atmospheric simulations. Therefore in WP1, available CCFs are systematically analysed, in order to identify and establish a direct relationship between impact and available meteorological and atmospheric data, e.g. temperature, humidity, geopotential, vorticity, to be provided as algorithm based ECF. In a similar way, this CCF approach is expanded to an ECF approach, by providing ECFs for air quality and noise, in a similar way as done for climate in REACT4C. Such temporally and spatially resolved information on environmental impact is integrated in a common framework and new metric, to be made available for ATM in an operational environment.
WP2: Environmental-optimized routing impact on ATM
WP2 takes into account other constraints (e.g. safety, fuel and other operating costs) on traffic routing for a selection of air traffic conditions and meteorological situations. In this work package, these flights are optimised to minimise environmental impacts, testing individual user preferences, e.g. contrail avoidance, minimal local impacts and assess the additional economic cost of these optimised routings. Further, the ATM implications of these operational strategies on the EATMN are assessed.
WP3 uses the algorithm-based ECFs from WP1 in case studies to evaluate and verify the applicability of these algorithm-based ECFs in real weather conditions. In this work package, air traffic flows are optimised to minimise environmental impact. This tests the robustness and feasibility of optimising European air-traffic trajectories with two different methodologies, simplified method (algorithm-based ECF) from WP1 and a more complete Earth-System Model simulation.
WP4 focuses on exploitation and implementation of project results. Additionally this work package is responsible to identify other possible metrics and assess the overall impact of climate-optimised trajectories in the context of these additional impacts, in order to reflect user preferences. It provides recommendations for intermediate solutions to minimising the total impact and provide a roadmap for how these solutions can be made more robust in the future.
WP5 performs the overall project management, including financial, legal and administrative management of ATM4E. The project management ensures an efficient project execution.
