This flight doesn't fly NATs, as it's departing too early in the morning...Westbound NATs concern only flights crossing 030W between 1130z and 1800z (please anyone correct me if I'm wrong).FLIGHT AF022/15MAY Random Track via 55N 3202NM(FPL-AFR022-IS-B772/H-SIJRWXY/SD-LFPG0625-N0479F360 EVX UT300 SENLO UN502 JSY UG4 LND UG45 LESLU/N0476F380UN522 DOLIP/M084F380 UN522 MALOT/M084F380 DCT 54N020W 55N030W 55N040W53N050W/M084F400 DCT YAY/N0489F400 N184B TOPPS/N0492F430 J581 ENEENE4-KJFK0718 KEWR-EET/LFRR0019 EGTT0042 EISN0103 EGGX0142 54N020W0206 CZQX025055N040W0332 53N050W0421 CZUL0531 CZQM0538 KZBW0616 REG/FGSPCDOF/020515)See the very hight FL430 filed from TOPPS... Not sure they're doing it systematically as planned...Yohann, LFLL.

That's interesting. I don't think I ever saw anything over FL410 filed (except for a Concorde of course) and I've never been over 410 in an airliner in FS either. I guess that 777 was kinda light then.Regards,Karl

Yes that 777 was very light (not much payload :'( ): it was already at FL380 over ireland...But I saw FL430 filed quite often lately for this flight, since northen canada went RVSM (NARs)...FL430 is also often filed for B744 and B772 bound to LFPG ending their trip from far east asia.Here's an example:FLIGHT AF275/24JAN Northern siberian route 5395NM(FPL-AFR275-IS-B772/H-SIJRWY/SD-RJAA0345-N0492F310 DCT SYE DCT GTC R211 AVGOK/K0903S1060 R22 QA R30 WADAZA333 TANAM/K0874S1160 A333 AGAMO/N0476F400 UN866 JNS UN624 KOSKAUL990 MARIP/N0479F410 UN850 MIC UA9 LBE/N0478F430 UR15 KENUM UM615IDOSA UN857 RAPOR-LFPG1224 LFPO-EET/UHWW0112 UHHH0133 UELL0255 UEEE0336 UERR0407 UOTT0453 UOOO0557USDK0623 UUYW0704 ULAA0730 ULLL0851 EFES0912 ESOS1008 ESMM1028EKDK1058 EDWW1107 EDLL1132 EBUR1148 LFFF1157 REG/FGSPN DOF/020124)NB: S1060=F347 / S1160=F380But I was told that airmen dislike getting that high for two reasons:- high alt radiations- a cabin depressurization would be too dangerous, with only a few seconds to rush to oxygen masks before faintingSo I'm not pretty sure it's flown "as filed"...Yohann
