GEESE will develop with SESAR the introduction of Wake Energy Retrieval (WER) operations within Europe. Two solutions will be developed in GEESE, and a transversal Wake science work package: The first one is "Enable Europe to North Atlantic WER Operations". This Solution will continue developing and refining the initial Concept of operation (CONOPS), its Safety assessment, analyse impacts on legacy systems, and develop simulations and trials to assess assumptions. ANSPs Partners, together with EUROCONTROL, Airlines, will particularly develop the Pairing Collaborative Decision Making (CDM) between Airlines Operational centres, Network Manager, and Air Traffic Controllers. Simulations will help consolidate the CONOPS, as well as trials will demonstrate the feasibility to develop the pairing CDM, and test it in real condition (with passenger airlines). Safety and Regulatory aspects will be addressed, as well as the economic benefits with a CBA (Costs Benefits analysis). TRL6 is targetted. The second solution is "Scaling up the WER concept to continental Europe". This Solution will provide operational solutions for the extension of Wake Energy Retrieval operations within European domestic airspace. Traffic flows from Europe to Asia, from Europe to the Middle East and from Europe to Africa are particularly interesting for WER application. CONOPS definition and assessment with simulations with ANSPs, ATC system providers, Network Manager and Airlines expertise will be conducted. TRL4 will be reached. As an enabler to operations, a Wake science work package will investigate transversal science-based aspects of operations, such as non-CO2 potential benefits of formations, in addition to better known CO2 benefits, and as well better understanding of the vortex behind the pair to support regulatory separation.

The Project encompasses the industrial research aimed to timely and efficiently create and use airspace capacity, in combination with targeted, effective demand and/or capacity measures. As such, it will focus on advanced levels of dynamic airspace configuration, Leveraging different virtualization models, digital INAP applications as well as Network-wide monitoring, all with high levels of automation. The project addresses the R&I need for on-demand air traffic services reflective of traffic demand, and the continuity of ATM service despite disruption. The project exploits the latest advancements in artificial intelligence and machine learning, to supply a variety of supporting toolsets to ATM stakeholders that enable rapid exploration of options for the deployment of capacity-on-demand solutions, whenever and wherever required. The benefits include increased en-route capacity and improved cost-efficiency of ATS provision, without compromising the current safety levels.

This project aims to refine and complete the definition of the common ATM U-space interface by identifying new working areas with impact and providing a consolidated interface with a standardized data model, architecture and an operation method to achieve a minimum TRL7. This proposal addresses the topic “ATM – U-space Interface and Services” which is composed of the following solutions: - Solution 1: ATM - U-space Interface:. Achieve full integration of ATM and U-space systems, by refining and completing the definition of the common ATM U-space interface and identifying new working areas with impact on the already started common interface. - Solution 2: Dynamic Airspace Reconfiguration: Develop the complete service mentioned in U-space regulation and in their respective Guidance Material (GM) and Acceptable Means of Compliance (AMC), necessary to stablish the operating methodology and develop the standard interface to help ATC actors in charge of airspace reconfigurations to maintain traffic segregation and to avoid proximity between manned and unmanned aircraft within the designated U-space airspace.

CONCERTO aims to provide the means to maximize the opportunities for CO2 reduction and to introduce non-CO2 impact management in daily operations. The goal is to reach TRL6 processes and tools that allow the ecosystem to achieve more eco-friendly trajectories and thus higher climate impact reduction without requiring major changes on legacy ATM and airlines systems. To do so, two specific objectives are declined for CONCERTO. The first one focuses on CO2 emissions reduction when the second one introduces non-CO2 climate impact reduction mitigation means. Finally, as CONCERTO is a data driven project, generating data on CO2 and non-CO2 effects and opportunities at TMA, ATSU and possibly network level, the project presents the opportunity to contribute to the improvement of european environmental performances dashboards. Ambition #1- Keep the pace on CO2 emissions reduction, integrate Green ATC capacity in ATM processes, with the appropriate level of automation, and support ATM actors in balancing permanently regularity and environmental performance at local and network level. Ambition #2- By leveraging state-of-the-art climate science, allow ATM actors to take their “eco-responsibility” to the next level Ambition #3- Strengthen cooperation, anticipation and exchange of information between NM, Air Traffic Control, Airlines and Flight Planning Service providers. Ambition #4- Demonstrate that mitigation measures such as the eco-friendly orchestrator and ECHO area avoidance concepts can be deployed progressively at network level, in close connection with scientific progress

The Air Traffic Control - Trajectory Based Operations (ATC-TBO) project proposes to validate TBO SESAR Solutions for flights in the tactical execution phase for en-route and TMA operations, thus contributing to the finalisation of the SESAR Phase C developed in SESAR 2020 and the realisation of the Digital European Sky vision in SESAR Phase D. The results are expected to contribute to capacity, operational efficiency, safety, environment and cost efficiency. The SESAR Solutions, with the TRL/EOCVM levels at the start and end of the project are: • Solution #4: Improved automation in sector planning and separation management via enhanced trajectory predictions and controller tools, including the completion of Solution 53A from SESAR 2020 to V3 (Initial = TRL4/V2; Target = TRL6/V3) • Solution #5: Improved air/ground trajectory synchronisation via lateral and vertical complex CPDLC clearances to support TBO, including completion of Solution 56 from SESAR 2020 to V3 (Initial = TRL4/V2; Target = TRL6 /V3) • Solution #6: Advanced separation management function concepts and tools, making use of more reliable trajectory information and advanced use of datalink/CPDLC (Initial = TRL1/2 (V0/V1); Target = TRL4/V2) The ATC TBO project consortium - with EUROCONTROL as the project coordinator, and steering from the PMB and the SJU - brings together 14 ANSPs, 1 airspace user, 10 airborne and ground industry partners, 5 research establishments, and 1 university. 14 EU member states, Switzerland and the UK are represented. The proposal describes 21 validation exercises including real-time simulations, fast-time simulations, and expert groups. The 'design', 'development & validation', and 'data pack & maturity gate' phases are planned for the second half of 2023, 2024, 2025 and the first half of 2026.
