Iīd really like to start a argument here:
Modern aircraft donīt need to use magnetic bearings to get around. Why doesnīt the aviation industry just quit the use of reference to the magnetic poles, they are constantly moving and are troublemakers, and stick to true instead of magnetic. We could of course have the spiritus forte compass and when in doubt would use it to verify our heading (even though the Sun is more accurate (not the newspaper)).
This doesnīt represent my opinion, but what wonīt be done for the sake of a good argument
