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.

Effective 27 November 2025 Relevant to: EGSS; LTC North Introduction Changes to SIDs from London Stansted (EGSS) have been implemented affecting repositioning flights to EGLL/WU and traffic leaving controlled airspace via BKY. LAM SID Removal The Lambourne (LAM) SIDs from both runways have been removed. Traffic re-positioning to Heathrow (EGLL) and Northolt (EGWU) shall now file and be cleared via a CLN SID departure, then DCT LAM. The coordination process for these departures remains the same. TC NE shall coordinate with TC Heathrow to vector traffic after departure towards the Heathrow RMA. EGSS-EGLL/EGWU FPL Route: CLN DCT LAM Max RFL: Minimum Stack Level BKY SID Revision The Barkway (BKY) SIDs, for traffic repositioning to Luton (EGGW) or leaving controlled airspace north of BKY, previously terminated at the boundary of controlled airspace. The SIDs have been revised to terminate at BKY, and the designators incremented accordingly.
