Thanks for all the replies!
I know the "Pole is AP" trick, but it works only in vicinity (~2° as the books say) of a pole.
What do I do at, say 75° Lat? Or at 80°?
I found this page and it is a good insight (on the topic of the Grid Navigation) but too much about gyrocompasses. I need similar (beginner's) material with more attention to sights and reductions.
