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.
