Just jumping into this thread now with another question. I'm planning a flight from Rotterdam (Netherlands, EHRD) to one of the fields south of Heathrow (not yet decided which one yet, but I've got some business to do there). The route will be direct over the sea, to the VOR (forgot its ident) which sits conveniently on the south bank of the Thames. I planned to report at one of these five-letter IFR intersections that mark the FIR boundary (they're in the GNS430), but does London Info have that information as well? Or should I report "at the FIR boundary, 51.30 North" or something like that? And can I put the same point in my flightplan? (EET/XANEB0110 or something like that)
