Description

The major part of data message interchange in the Aeronautical Fixed Service (AFS) is performed by the Aeronautical Fixed Telecommunications Network (AFTN). Unfortunately the AFTN technology is now outdated. Its upgrade - the Common ICAO Data Interchange Network (CIDIN) - was conceived in the 1980s and is now itself nearing obsolescence. Both AFTN and CIDIN need to be replaced by more modern technology. To meet this requirement, the ICAO has specified the ATS Message Handling System (AMHS).

The AFTN, CIDIN and AMHS together form an integrated, heterogeneous data messaging environment, collectively referred to as "ATS Messaging." Because of the distributed nature of these networks, and of the co-operative way of operating them, evolution has to be progressive from one technology to the other. During transition from AFTN and CIDIN to AMHS, messages will be exchanged seamlessly between users of all networks.

The ATS Messaging Management Centre (AMC) provides centralized off-line management services in support of the ground ATS Messaging network of Air Navigation Service Providers (ANSPs) in Europe. More details on the AMC services can be found in the in the ICAO EUR AMHS Manual.
