One way to deal with unreliable magnetic compasses in the arctic is to use an astrocompass to check variation and deviation as done on this Boeing 737.
An interesting video. Is the astro compass being used because it is part of company procedures or are the pilots navigation enthusiasts who are just as likely to pull out a bubble sextant?
