Data link common services will optimise the use of existing air-ground and airborne resources by relying on the ground distribution and sharing of air-ground data.
This specification contains requirements for the ground implementation of data link common services for the Aeronautical Telecommunications Network (ATN) as defined by ICAO Annex 10 (Volume III, Part 1). It includes general, functional, performance, configuration, management and monitoring requirements for a Logon Service (DLIC) and an ADS-C common service. It relies on the EUROCONTROL Specification for Data Link Ground Distribution SWIM Services for ground distribution.
The specification is supported by EUROCONTROL Guidelines for Initial Trajectory Information Sharing.
