The purpose of the airspace data management is to organise and provide all necessary airspace information to feed the core Network Manager Operational systems (Integrated Initial Flight Plan Processing System (IFPS) and Enhanced Tactical Flow Management System (ETFMS)) and the systems of our operational stakeholders. The information we provide consists of:

  • ECAC airspace infrastructure (published officially in the AIPs),
  • Operational unpublished data collected from ANSPs (taxi-time, sectorisation, etc.),
  • specific non AIP data required to perform the ATFCM/ASM function (such as Traffic Volumes),
  • airspace management operational data required for EAUP/EUUP publication,
  • restrictions implementation required to validate Flight Plans, and
  • library with addresses for distributing ETFMS/IFPS messages/parameter settings to AOs and ANSPs.

The Network Manager Operations Centre (NMOC) filters this information and uses it to update the Central Airspace and Capacity Database (CACD) (common airspace data repository feeding operational systems and enabling aeronautical data services). The airspace data is validated prior to distribution.

This activity leads to dynamic, semi-dynamic (during the current Aeronautical Information Regulation and Control (AIRAC) cycle), or static (for the next AIRAC cycles) systems database updates.


  • Central Airspace and Capacity Database (CACD), or environment data updates accessible through the Collaboration Interface for Remote Environment Access (CIREN),
  • environment (ENV) dossier,
  • electronic restrictions published via the Network Manager business-to-business (NM B2B) web services,
  • e-AIM via NM B2B web services and European Airspace Use Plan (EAUP), or Update Airspace Use Plan (UUP) via the Network Operations Portal,
  • operational airspace data needed for restrictions and all the objects that are referred to via NM B2B web services.
