On the night of 27/28 June 2013 the FMTP connection between Zagreb and Budapest was put into operation, after the last tests had been conducted.
The Flight Message Transfer Protocol (FMTP) is a new network protocol which, following the transition to more current means of communication and making use of standard network technologies (TCP/IP), enhances the former mode of flight data exchange b etween adjacent air navigation service providers.
The X-Bone Network, defined and set up within the Functional Airspace Block of Central Europe (FAB CE), was the basis for the establishment of this connection.
This transition fulfils the requirements set in the EU regulations (Single European Sky Interoperability Implementing Rules) stipulating the transfer to a new standard of flight data exchange for all European air navigation service providers.
Tests and preparations for the transition to other neighbouring ATC centres that has established the flight data exchange with CCL are in progress.
