After the success of the deployment in Brest in March, Thales's Green Flag Orchestrator tool has been implemented at the Reims Area Control Centre (ACC) in France, reducing the consumption of fuel per optimised flight by 200 to 300kg.

Green Flag Orchestrator provides Air Navigation Services Providers (ANSPs) with more eco-friendly opportunities', allowing airlines to optimize flight plans, thereby reducing plane fuel consumption and greenhouse gas emissions.

This initiative is part of the EU-funded SESAR JU CONCERTO project, which aims to optimize CO2 reduction opportunities and integrate sustainable air traffic control practices.

CRNA Est, Reims Thales and France's Direction des Services de la Navigation A rienne (DSNA) announce the successful implementation of the Green Flag Orchestrator solution at the Reims Area Control Centre (ACC) in France. This milestone marks a new significant step towards more sustainable aviation and aligns with the European Unions environmental goals to reduce 90% of CO2 emissions by 2040.

Using advanced decision-making algorithms, Thales's Green Flag Orchestrator is a tool for ANSPs to manage ATC (Air Traffic Control) constraints' - restrictions imposed by ATC to ensure the safe and efficient movement of aircraft through controlled airspace, such as altitude restrictions. This tool automatically identifies and suggests opportunities' to relax some of these constraints', which are then proposed to airlines, enabling them to optimise their flight plans, thus reducing fuel consumption and CO2 emissions. By ensuring automation and digital coordination, this solution optimizes ANSPs' workload, while maintaining the same levels of safety and capacity.

This deployment is part of the EU-funded SESAR JU CONCERTO project, which focuses on integrating new technologies and concepts to reduce CO2 emissions and introduce non-CO2 impact management into daily operations. As part of this project, all CONCERTO partners are working to integrate green air traffic control capabilities into the system, balancing capacity and environmental performance.

The integration of the Green Flag concept at Brest and Reims ACCs aligns with our commitment to promoting a greener aviation industry. This initiative is a crucial step in our environmental strategy and supports our goal of reducing the sectors carbon footprint. Florence Serdot-Omer, Head of Unit Validation of Concept and new Technologies at DSNA.

Combining advanced algorithms and collaborative tools, the Green Flag Orchestrator empowers Air Navigation Service Providers and airlines to make environmentally conscious decisions, and unlock numerous opportunities for flight path optimization, paving the way for a more sustainable future in air traffic management. David Antonello, ATM Green Operations Lead at Thales, and CONCERTO project leader

Congratulations to Thales and DSNA for the successful deployment of the Green Flag Orchestrator in Reims and Brest. This achievement, delivered through the SESAR CONCERTO project, is a great example of the SESAR innovation pipeline in action-transforming promising ideas into tools that deliver immediate environmental benefits. By accelerating the uptake of eco-efficient solutions like this, we are helping to make Europe's skies more sustainable, flight by flight. Andreas Boschen, Executive Director, SESAR Joint Undertaking.
