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 details the SWIM services of the Logon Service and an ADS-C common service defined by the EUROCONTROL Specification for Data Link Common Services for the Aeronautical Telecommunication Network (ATN).
The specification is supported by EUROCONTROL Guidelines for Initial Trajectory Information Sharing.
