Mag2True – Aviation Heading Reference Transition Action Group

The International Association of Institutes of Navigation has taken up the initiative to transition to true tracks in aviation. To this end, IAIN established a “Mag2True Working Group“. This page provides information on the Working Group. The group, which is now formally called “Aviation Heading Reference Transition Action Group”, holds regular on-line meetings. The secretary can be contacted via email at
