Since June 2013, the Functional Airspace Block Europe Central, known as FABEC, has officially been in operation. On the basis of a treaty ratified by the six States of Belgium, France, Germany, Luxembourg, the Netherlands and Switzerland, the civil and military air navigation service providers (ANSP) have worked in close cooperation to improve safety, efficiency and cost-effectiveness, to ensure punctual flights by providing the capacity required, to reduce emissions and to offer more direct routes to airlines.
FABEC cooperation strengthened during COVID-19 in response to the unprecedented traffic downturn. Despite diminished financial and staff resources, critical airspace infrastructure remained open day and night to ensure essential medical supplies, cargo and repatriation flights arrived safely at their destination. FABEC took the opportunity to accelerate cross-border initiatives including more direct routings and greater data exchange between adjacent centres.
