CRCO - Central Route Charges Office
Airspace users which fly in the controlled airspace of EUROCONTROL’s Member States pay for the air traffic services they use.
EUROCONTROL’s Central Route Charges Office (CRCO) charges airspace users for these services on behalf of the Member States.
The CRCO calculates the route charges due to the Member States for the services provided, bills the airspace users and distributes the route charges to the States concerned.
