2025-11-20 - [Enroute] LAC West - Splitting Procedures

[VATSIM UK Operations]

Valid 1800-2230z 20 November 2025

For the 'Dublin Thursday Night Live" 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.

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.
