Grid Navigation?

[quid]

We are looking at flying near areas of magnetic unreliability, i.e., Greenland. Where can I go to find information on grid navigation?

Publications? Web sites? TIA

USAF P 11-216, Air Navigation. Chapter 14 is all about grid nav.

Good starting point, I'd think.

grid navigation for Greenland is a little over the top. Greenland is far enough east of the magnetic north pole that it shouldn't be a problem. The only exception might be the northern tip. Where in Greenland are you going to be flying?

Have operated over Greenland many times in B707, L1011 and FH227B aircraft using either GPS, INS or VLF/Omega...no problems noted at all.

We'd be operating into Thule. I know it's not in the area of AMU, but close enough that we'd like to be familiar with Grid Nav. All we have is GPS. If the GPS fails, we'd like to have a back up plan. Ops Specs B040.

av8boy- Good reference. 15-20 minutes of study and I should have it down pat. :D

Thanks to all.

you won't have any problem with the compases in Thule. The hardest bit is getting used to the white runway. Have fun,
