Aerospace/Aviation - a navagation question


Expert: Capt Paul - 10/31/2006

Question
If I am over the geographic north pole what heading would I fly to get to Seattle?  Or Toronto, or anywhere?

Seems to me the minute you leave the pole your heading for anywhere and forget the magnetic aspect, will by 180 degrees.  

What am I missing here?  That can't be right...

Answer
If your over either the geographic north pole, or the magnetic north pole, you would be flying what we call "Grid Tracks".  Simplistically, it's a track based navigation, opposed to heading based system.

Because the magnetic poles and geographic poles are located in different places, the magnetic compass becomes somewhat useless in the far northern regions.

But, your magnetic heading would be a little more accurate when flying from the magnetic north pole, which is located somewhere around northern greenland.  However, it does move slightly eash year.

Hope this helps.

Cheers
