2025-12-12 - [Enroute] LAC West - Splitting Procedures

[VATSIM UK Operations]

Valid 12 December 2025

For the "Channel Islands Christmas Shopper" event a temporary arrangement is made to allow for the splitting of LAC West.

Division Policy on bookings remains unaffected. LON_W_CTR remains the only primary or secondary position in the LAG West group. However, if required due to controller workload, other positions in the West LAG (defined in this post) may be opened without the rest of West being staffed.

Controllers operating splits positions must provide a link to vatglasses.uk/ukireland/ in their Controller ATIS.

Any errors in procedures should be reported to the Operations department via the Helpdesk or Discord.

Agreed Levels

Controllers are advised to use the "LAC West (North Sheet)" and "LAC West (South Sheet)" level diagrams for splits. The following agreement in addition is the only agreement from Berry Head to Brecon:

To	Agreement	Conditions
Brize Group, EGBB, EGBE	FL240 lvl EPACE	-

 

Coordination with Adjacent Units, Sectors and Airfields

Brecon and Berry Head controllers must inform all adjacent controllers when the split is opened/closed. Neighbouring ACCs are aware of these procedures, however, adjacent UK controllers (enroute, approach and aerodrome) may need guidance on top-down coverage and transfer of traffic.
