Like a bird, a moving airplane leaves a wake of disturbed air, creating an updraft that allows a following aircraft to cut down on engine thrust, fuel use and emissions.</p><p style="text-align:justify;">Led by Airbus, the project will bring together a range of stakeholders, including Eurocontrol, DSNA, Air France, On, Indra, ENAC, DLR, AirNav, Bulatsa, CIRA, UAB, Frequentis, Boeing, French Bee, NATS, Virgin and Delta Airlines, to investigate how to introduce WER into air traffic operations.</p><p style="text-align:justify;">CIRA participates in the GEESE project through its Laboratory of Autonomous Intelligent Complex Systems (SCIA) within the Reliability and Safety Unit (AFSI). SCIA will support the definition of CONOPS for pilots and air traffic controllers, thanks to the Multiagent Simulation Facility (MASF) that allows to assess the impact on safety and human factors.</p><p style="text-align:justify;">WER sees a pair of aircraft flying in formation, one around 3km behind the other, allowing the trailing jet to benefit from the lift generated by the preceding aircraft's vortices, reducing the thrust required from its engines. The initial modelling suggests airlines could save between five and ten per cent of fuel per trip. </p><p style="text-align:justify;">Specifically, the project will elaborate an initial concept of operations (CONOPS) to enable Europe to North Atlantic WER operations, analysing safety aspects and the impact on legacy systems. The project will also provide operational solutions for the extension of WER operations within European domestic airspace.<br></p><p>For more information click <a href="https://www.sesarju.eu/news/geese-how-migrating-birds-are-inspiring-more-sustainable-aviation" target="_blank"><strong class="ms-rteThemeForeColor-5-0" style="">HERE</strong></a><br></p><p><br></p><p><br></p> | 2023-07-20T22:00:00Z |
