Hello!I downloaded the following FP from fboweb:KATL..EATWO..GRD.J209.RDU.J52.RIC.J14.PXT.J191.RBV..JFK..PUT..BOS..TUSKY.N63B.VIXUN.NATV.NIBOG.NATV.NURSI.UN551.BESOP.UP6.REMSI.UL603.DIDAM.UL603.TESGA.UZ729.BOMBI.T104.WLD.WLD5M.EDDMThe questionWhat does TUSKY.N63B.VIXUN mean? The North American Routes program comes into the game. Correct? But how to "translate" N63B?Thanks for help,Tom

Hi ! well actully the N63B is TUSKY DIRECT VIXUN pretty neat eh? im not 110% sure about this so maybe Koean can give u a better answear.Best regards: Alexander

Hello!Great ;-) Why do they need to include N63B? Both WP are already in the FP.Thanks,Tom

There are several NARs available for each NAT track, to relieve traffic congestion. This way when aircraft from many different directions want to fly to their intended track's inland fix, they aren't mixed up with converging traffic at 45 degrees.They are meant to act as a transition between Oceanic and Domestic airspace.There are a few links which outline the procedures and goals of the program which probably describe it better than I do ;-)http://www.nat-pco.org/nat/MNPSA9/mnps9_r.pdfhttp://www.bostonartcc.net/fps/NAR.pdf

Hello!Now I know the general system. Is there any website which publish the current NAT roues?Thanks,Tom
