Flight message transfer protocol address coordination

At EUROCONTROL, we report on the implementation of the Flight Message Transfer Protocol (FMTP) on behalf of the International Civil Aviation Organization (ICAO).

Flight Message Transfer Protocol (FMTP) is a communication stack based on the transmission control and internet protocols (TCP/IP). It is used in a peer-to-peer communication context for the information exchange between flight data processing systems for the purpose of notification, coordination and transfer of flights between air traffic control units and for the purposes of civil-military cooperation.

FMTP database

To do so efficiently, we use the FMTP database, which follows the implementation progress of each air traffic control unit and includes a contact point for correspondence, technical capabilities, supported OLDI messages and communication links with peers.


We have also developed technical guidelines, specifications and other supporting documentation to help critical ATC data exchanges over TCP/IPv6. The document is available for download to help our stakeholders with the transition to FMTP.
