This implementation Project (IP) aims at upgrading the French Control and Reporting Centres (CRCs) to maintain interoperability with French Civil Air Navigation Service Provider (ANSP) Air Traffic Control (ATC) system (4Flight).

This Implementation Project is a prerequisite to the operational deployment of 4flight in civil Air Traffic Control (ATC) centres to assure the non-deterioration of the civil-military IOP (interoperability) services that were made available using CAUTRA (previous civil ATC system). To maintain interoperability from the outset of 4Flight implementation plan (including test phases) military had to develop a programme to upgrade military systems.

This upgrade solution should provide military CRC with the indispensable capability to receive and process civil fight plans, and to perform any coordination activities between civil and military controllers which are necessary to provide simultaneously en-route services, and to perform air policy and search and rescue missions.

This project is also a prerequisite to the implementation of Free route in French airspace as it relies on a robust civil/military coordination.

The project encompasses two main objectives:

-The upgrade of current military CRC system to maintain civil-military interoperability during all the 4Flight deployment phase and from 2018 the implementation of a specific interface that will allow exchange of Air Traffic Management (ATM) data between 4flight and the next generation of CRC system planned to be deployed during the same period.

-The deployment adress directly the upgrade of the ATM systems, precisely between civil ATC and military AD system. It will enable Flight Data Processing System (FDPS) functions of the CRC system to data correlation as well as flight identification which is also one of the main functions of the Air Defense (e.g in the cross-border control).

This new capacity will also prepare the deployment of the foundations for the upgrades of the Air Space Management (ASM) for Free Route Airspace (FRA) management. Military system will be able to process flight data for Direct (DCT) flights.
