One that gets me is on Seaford sector at Latcc. The biggest problem is jumbling around the traffic to make the phenominal amount of level capping restrictions imposed by the French agencies. How many times have I been asked 'could you please pass on we're looking for FL330 today' for a/c restricted AND flowed at FL270. a) normally haven't got the time; b) this means telling a different agency ie Brest who won't even have skeleton details on your flight so won't care anyway; c) its much easier if you ask Paris, at least when they speak to Brest they can do it in the same language!
Similar to this is the 'heavies' climbing out of London going to Africa et al, who cannot make FL290+ by Etrat/Bames. These are passed at FL270 max to Paris, so at least when they transit the airspace, Paris can see them and then attempt separation from the CDG inbounds. Telling us that FL330 is the final level is pointless, you still going to Paris.
Well done to the Jersey/British Euro boys though who have us sussed. Asking for FL290 and also informing us you can be level is totally spot on. It saves us a transmission and you then going 'errrr....I'll just check, standby'!!!! <img src="wink.gif" border="0">
Merry Christmas everybody and , as I was reminded yesterday, have a HAPPY NEW YEAR!!!!!!!
