An XML Datalink Message Exchange Model (DMXM) for command and control data sharing

ATC services use datalink communication systems such as FANS/ACARS, FAA DCIS and EUROCONTROL DLS/Link2000+. This communication domain, specific for ANSP safety applications, uses dedicated Communication Service Provider (CSP) networks, such as Rockwell Collins (ARINC) and SITA. A need has been identified in the broader aviation community to share the updated status of ATC instructions and clearances with stakeholders other than the ANSPs. This information sharing capability should use the widely-accepted XML data format in order to leverage open publish/subscribe services, and SWIM architecture and governance. Therefore, a standard data model and interface should be defined.
