Aircraft can provide essential information to support accurate and reliable trajectory prediction or alternative scenarios during the execution of a flight. The EU-funded PJ38-W3-ADSCENSIO project will improve several characteristics of air traffic control through the better prediction of flightsâ behaviour. The project demonstrated the improvements in several operations performed by air traffic controllers as well as the efficiency and strength of a technological infrastructure to support the data link communications between the aircraft and ground on trajectory-related exchanges. The adoption of technical and operational solutions reduced controller workload in high traffic conditions, increase airspace capacity, and reduce flight delays, fuel consumption and CO2 emissions. https://cordis.europa.eu/project/id/101017626/results 27/06/23
