I have entered a route into FSBuild but it will not recognise the airways. I suspect they might have changed, could someone please help me in finding the right ones.Here's the route I've planned:LFPG-NIPO9B-GES-UP605-MALIV-UM611-SORLA-UH24-VI-UG59-GR-KTL-B22-ZJ-B200-UF-A575-ERE-B328-WXI-A461-VHHHThanks-Mikkel

I suspect you need to update your navdata Mikkel.I have autogenerated a route in FSBuild but it gets lost part way through the route so I did one with FSNav which is what I use for planning.The route is more involved than your simple one and with a bit of tuning in FSNav I may be able to reduce the number of waypoints, but here it is as generated.NIPOR UH101 RANUX UN858 LIMGO UZ111 OBIGA UL984 BOMBI UZ728 MASEK T200 ABVIG UZ21 TADUV Q200 GOVEN UL979 SUMOK UA260 VTB UN858 RATIN R11B FK 6COR3 UM 6E11 BP 6E17 RW 6E23 SF R480 RP R488 OK A300 NEDRA G553 RILAN R480 LANTO G540 WW R482 UAUU G11 ATBAN A95 KRG A368 FKG B215 DY B330 POU R473 SIERA BTW You may want to try http://rfinder.asalink.net/ and see if that gives you a better route to enter into FSBuild.HTH
