Operational Needs

Air traffic management is defined by ICAO as the "dynamic, integrated management of air traffic and airspace including air traffic services, airspace management and air traffic flow management - safely, economically and efficiently - through the provision of facilities and seamless services in collaboration with all parties and involving airborne and ground-based functions".

Stakeholders involved in air traffic management need aeronautical data concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential for flight operations.

This service satisfies this need by allowing clients to subscribe to event scenarios and to be notified when the aeronautical data described in the event scenario is affected.

The aeronautical data can be used, e.g., in pre-flight information bulletins. It can also be used to improve decision making thus positively impacting the efficiency of their planning and flight executions, enabled through automatic data verification and graphical visualisation. The aeronautical data is also used in other systems such as those used for airspace reservations (ARES). A list of these is available in Appendix C.

This service satisfies this need by offering the aeronautical data (in the form of event features) as regulated by ICAO Annex 15 - Aeronautical Information Services.

The scope covers the event encodings outlined in the Digital NOTAM Specification including aerodrome data for the 18 airports listed in EU Implementing Regulation 2021/116 - Common Project One.
