Airway routes over the Mariana Islands NW Pacific
Hi Guys,
My wife is working on a university project regarding the hazards to aviation of volcanic ash. She has asked me if I know the routes over the NW Pacific, unfortunately I only fly in UK so do not have a ready answer
.
Could any one help on this please? Are any of the charts available on the net (FAA)?
Many thanks

Nopac Flying
I have been retired now for 6 years,so my memory is a little sketchy and possibly out of date. I am responding only in the absence of more informed information.
There are 4 or 5 fixed tracks, about 60nm apart, beginning over mainland Alaska and then straddling the Aleutians to Japanese airspace. There is a whole list of rules as to when, and at what FL, and in which direction they may be flown.
In addition there are 2 or 3 random tracks issued by Oakland Center for westbound traffic between about 2000Z and 0800Z (approx). These tracks
never are closer to the above mentiontion fixed tracks than 100nm, and
are regulated as to available FLS.
Tokyo issues a set of 2 or 3 eastbound random tracks for use between 0900Z and 2100z (approx) and are regulated as above for FLS.
Their were proposals when I left to allow complete random tracking in both directions by all aircraft, at least south of the fixed NOPAC tracks.
There have between many eruptions of volcanoes in Alaska and Russia, including one just west of Anchorage that affected flights into and out of that airport.
I hope this is of some help. or at least prompts more recent/accurate info.

The North Pacific 1/2 and 3/4 Jepp Enroute charts as well as the Far East 7/8 have Pacific routes on them. There are the NOPAC routes from Alaska to Japan, routes from the US West Coast to Hawaii and on to Guam, and routes from Guam to Japan.
