I recently did a flight from EGLL to KPHX and half way across the atlantic I was told I was off course by RC. Did my FP in FSBuild following Great Circle route and NATS for the day.Saved it into flight/myflights. Loaded it into my FMC (Just Flight 777) and also loaded into RC. Checked and re-checked route to make sure both corresponded and all was OK. However at about 5530N RC informed me I was off course.Some of the Lat/Long weigh points were over 300 miles distance. Would this have affected RC's behaviour bearing in mind that we are following a great circle track?In anticipationDavid

i found this problem, too. i think. the beta testers will be testing in the next couple of days, and i will upload the new build if things workedjd

Thanks JD.I will keep a watch on posts.
