Magnetic Compass Induced Errors The magnetic compass is the simplest instrument in the panel, but it is subject to a number of errors that must be considered. Variation The Earth rotates about its geographic axis; maps and charts are drawn ... geographic poles. Directions measured from the geographic poles are called true directions. The magnetic North Pole to which the magnetic compass points is not collocated with the geographic North Pole, but is some 1,300 miles away; directions measured from…
