I nreply to your question about EGLC, the change is all to do with new NERC procedures. Presently all the `Alkin` arrivals (LC,KB,MC,TO) route via LYD VOR but at NERC, to keep the traffic wholly within Sector 20 (Dover Low) rather than Sector 19 (Lyd). To do this, the traffic has to re-route via the new point ROKOS and then to SANDY. Hope this is of some use. Cheers, BB.
