Every month, we publish data related to the last monthly billing. We also provide and update an online Service Units Dashboard to help States and airspace users analyse their monthly billing data. This dashboard contains various visualisations and tools for users to understand the monthly evolution of en-route service units across the year as well as a comparison with past plans.
Monthly follow-up of service units in 2017
Data are provided monthly for each of the EUROCONTROL charging zone, for the CRCO Total and for ESRA02 (the EUROCONTROL 2002 Statistical Reference Area consisting of the 30 first charging zones). The tables and charts show total service units i.e. the sum of chargeable and exempted service units.
After each monthly billing, CRCO updates the monthly service unit figures recorded for the previous flight months of the current year in order to take account of additional flights billed and credited. This information is shown in column (1) of the table in the state-specific sheets in the “Monthly follow up” documents above. The corresponding service unit figures in the “Monthly follow up of service units” match the service unit figures as published on the DashBoard.
In January 2018, the resulting CRCO total for 2017, as shown in the “Monthly follow up of service units”, will be published in the 2017 Report on the operation of the route charges system.
