pending 2025-05-15 - [Enroute] LAC South - New French Sectorisation and Callsigns

[VATSIM UK Operations]

Effective 15 May 2025

The French vACC have made significant changes to their Paris and Reims sectorisation which have been reflected in a new Letter of Agreement (LoA), effective AIRAC 2505. We have also taken this opportunity to review how the French APP units Iroise, Rennes and Lille are reflected in the sector file and our documentation, as well as a review of release procedures. Please also see these additional posts which relate to this LoA update:

• 2025-05-15 - [Enroute] LAC South - Revised Agreements and Releases with French vACC
• 2025-05-15- [Enroute] LAC South - New COP UTFAV replaces RINTI at FL195+

Summary of Changes to Sectorisation

• The Divisional Flight Level (DFL) between Paris and Reims ACCs is lowered from FL295 to FL265
• Paris Control sectors now use the callsign prefix PAR (previously LFFF)
• Paris North is divided into its three real world constituent sectors, TN, TP and TB, each with its own available position and frequency
• Reims North is divided into three new constituent sectors, UN and UB (FL265-FL345) and HN (FL345+)
• An area of airspace south of UTFAV (the new RINTI) is delegated from Paris TB to Reims UB from FL195 to FL265 (this is not drawn on the maps below)

⚠️ Controllers must ensure the sector file is updated to ensure the new positions are identified and the ownership/next sector prediction functions correctly.

The following sections are included at the end of this post:

• Appendix A - Paris Sector Map
• Appendix B - Reims Sector Map
• Appendix C - Interface Cross Sections
• Appendix D - LoA Excerpt

 

Documentation Status

The significant number of changes to the London (EGTT) vMATS Part 2 have not been reproduced here. The document will be updated for 2025/06 (June AIRAC).

The Agreed Levels Diagrams will be updated to coincide with this change. Revised versions will be available at docs.vatsim.uk/Enroute from the effective date.
