This Implementation Project aims at developing an incremental and fundamental step of the Coflight-eFDP (a new generation of FDP - Flight Data Processor) System that will meet the needs of European Air Navigation Services Providers (ANSPs) for the next decades satisfying the need for the harmonisation of Air Traffic Management (ATM) systems in Europe.
This Implementation Project will deliver the Version 3 Release 3 (V3R3) FDP version that will be used by the French and Italian 4-Flight ATM Systems.
The Coflight version V3R3 will provide the following major features:

1. Increased operational, technical and economic efficiency in the implementation of Free Route Airspace (FRA):

• Increased interoperability, improved trajectory prediction;

• Further lowering of FRA level, making use of automatic conflict detection tools providing vertical and horizontal exchange assistance

• Dynamic Lat-Long Cross Area of responsibility (AoR) Points (COP) enabling Functional Airspace Block (FAB) and Regional Free Route;

• Increased operational flexibility in the configuration of the airspace volumes;

• More precise airspace configuration planning in order to accommodate traffic demand in an improved cost-effective manner;

• Increased automation, through implementation of Air Traffic Controllers tools;

1. Improvement of robustness related to exchanges of information between Aeronautical Fixed Telecommunication Network (AFTN) station (Coflight) and
   Communication Centre in accordance with “ICAO Annex 10 volume II Communication Procedures”.
   It concerns the service messages used to ask the re-emission of mutilated, improperly formatted or non-received messages;

2. Compliance with latest cyber security requirements;

3. Implementation of requirements/needs coming from 4-Flight Programs.

This Coflight version V3R3 follows the version V3R1 developed and co-financed in the frame of the Action 2014-EU-TM-0136-M (#067AF5) that provided a first stable version of the Coflight Product.

During 2016-2017, a Coflight version, namely V3R2, was developed mainly as corrective version that also embarked some evolutions, especially requested by Italian 4-Flight as a result of gap analysis between Coflight and Italian legacy system.

The Coflight version V3R3 will be integrated in the version Build 3 of the Italian programme 4-Flight (2015_204_AF3_Phase_I & II, 2016_115_AF3) and in the French 4-Flight new ATM Systems, both planned to be put into operations by the end of 2021.

No interoperability based on ED133 EUROCAE specifications is foreseen to be implemented within this version V3R3, since it is still matter of validation under the SESAR R&D framework. The only interoperability that Coflight provides is a native interoperability among Coflight instances based on the Coflight internal version of the Flight Object.

• Specific objectives:
  The planned release of Coflight specifically aims to:

• Increase operational, technical and economic efficiency in the implementation of Free Route:.

• Improve the robustness related to exchanges of information

• Compliance with latest cyber security requirements;

• Implementation of requirements/needs coming from 4-Flight Programs;

• contribute to the wider programme that involves the renewal of the whole National ATM System, 4- Flight, for ENAV and DSNA.

• Expected Results:
  The implementation of the planned release V3R3 will support the Italian and French National ATM Systems Integration Programmes.

• Performance Benefits:
  Enhancement of overall ATM system performances (e.g. technical performances, reviewed procedures) thanks to the availability of the new version of Coflight in Italian and French ACCs:

• Increased interoperability, improved trajectory prediction;

• Further lowering of FRA level, making use of automatic conflict detection tools providing vertical and horizontal exchange assistance

• Dynamic Lat-Long COP enabling FAB and Regional Free Route;

• Increased operational flexibility in the configuration of the airspace volumes;

• More precise airspace configuration planning in order to accommodate traffic demand in an improved cost-effective manner;"
