The airborne services in D-AIM make use of data link to share information between the air and the ground. The services are well aligned with the services defined by RTCA Sub-Committee 206 and EUROCAE Working Group 76 for AIS/MET Data Link.

In the Operational Services and Environment Definition (OSED) for Aeronautical Information Services (AIS) and Meteorological (MET) Data Link Services as defined by RTCA and EUROCAE (document ED-151) the AIS Data Link services have been divided into two groups, Baseline Synchronisation and Aeronautical Updates. The MET Data Link services have been divided into Weather Planning Decision Service, Weather Near-TermDecision Service and Weather Immediate Decision Service.
All the applications above are applicable in the D-AIM context. The initial airborne applications addressed in the D-AIM trials would sort under the services mentioned above as follows:
AIS
ED-151 name: Baseline Synchronisation
- D-AIM trials: Web Feature Service (WFS) for Baseline data (Nav database, airspace database, Aerodrome Mapping database (AMDB), etc),
ED-151 name: Aeronautical Update
- D-AIM trials: Temporary Segregated Area (TSA) Status, RWY/TWY Closure Message
MET
ED-151 name: Weather Planning Decision Service and Weather Near-Term Decision Service
- D-AIM trials: Graphical METAR and graphical SIGMET (both via ground-to-air data link)
