Why no pacific track Lima on www.notams.jcs.mil

[CPA156]

HelloI am trying to plan a flight from Singapore to LA going something like:N0487F310 HOSBA G580 TOMAN M767 JOM/M083F350 Thats where I'm up to and I'm trying to get the PACOTS track L (from phillipines-west coast US) on www.notams.jcs.mil and its not published. Is there a reason for this? Are the Headwinds too strong? Does all traffic from the Phillipines from US go up via Japan this time of year?thanks

Hey I have just realised that track Lima is from US-Phillipines so I must have to go via japan. Would going on the NOPAC tracks be an option? Does anyone know if there is a place where the NOPAC tracks are published?

Hi Patrick,The PACOTS tracks are (like the NAT tracks) only published for routes where traffic regulation might be necessary. For westbound NAT traffic for example, usually 5 or 6 tracks are published, but on very busy days (e.g. summer holiday season) I've seen as much as 10.Looking at today's tracks, it seems track 14 or 15 will suit your flight best, but these are only available for traffic from RCTP and VHHH. So I think the best option you have, is to file a random route south of this track and join it at the end, if your flight is going to the KLAX/KSFO area. If you're planning a flight which needs a more northerly route, you'll have to file a random route north of track 1, which also doesn't conflict with the westbound tracks (check validity times, routes etc.).Cheers,http://home.planet.nl/~duijn181/cu2/koen.jpg

Koen do you know if the NOPAC or SOPAC tracks are published anywhere?

Hi Patrick,Actually the PACOTS tracks include all tracks through Pacific airspace, so they include both the "NOPAC" and "SOPAC" tracks. As you've seen, they're usually meant specifically for Asia-US traffic. For more northern routes (e.g. over Alaska), there's an airway system running along the Russian east coast, for flights between e.g. South America and Australia, random routes are used...Cheers,http://home.planet.nl/~duijn181/cu2/koen.jpg
