GEESE

Main Goals of the Project

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 GEESE project runs over 3 years and is executed by a team that consists with a mix of ANSPs, Defence and Aeronautics Industries, Airlines, Aerospace Research Institutes, ATM Technology and Industrial Solution Providers and Eurcontrol as the intergovernmental ATM organisation of Europe.

CIRA Activities in the Project

CIRA is involved in Solution 2: "Scaling up the WER concept to Continental Europe" for a validation exercise conducted in collaboration with the Universitat Autònoma de Barcelona (UAB). CIRA's contributions include:

• Supporting the definition of the exercise, which includes both a Hybrid Real-Time Simulation (HyRTS) and a Fast-Time Simulation (FTS), aimed at evaluating the impact of WER operations on air traffic and human operators.
• Contributing to the writing of the Validation Plan (VALP) for the exercise.
• Defining the procedures for the different phases of WER operations.
• Designing activity diagrams as input to the Multi-Agent Simulation Facility (MASF).
• Implementing the integration between the MASF and the X-Plane simulator to enable the exchange of CPDLC messages during the HyRTS.
• Adapting scenarios and procedures to allow the autonomous execution of FTS runs.
• Collecting and analyzing metrics to assess Key Performance Indicators (KPIs).
• Supporting the drafting of the exercise section of the Validation Report (VALR), including metrics analysis and operational observations.
