The use of X.25 data communication networks to support ground-ground ATS data exchanges is becoming increasingly costly and has a limited lifetime. As a consequence, it was necessary to adapt the former EUROCONTROL Standard for Flight Data Exchange Interface Control Document from X.25 to TCP/IP. This migration led to the development of the SES implementing rule and the EUROCONTROL Specification on Flight Message Transfer Protocol.
Both are in direct support of the Coordination and Transfer implementing rule and the EUROCONTROL Specification on On-Line Data Interchange (OLDI)
To support implementation, EUROCONTROL has also made available the ETIC test tool, FMTP test plans and additional guidance material.
