that instrument is tied into the Loran navigation system. it works sort of like a vor receiver (the two instruments on top of each other on the right side of the pilots instrument panel.....) in this plane however it has only worked correctly for me once so i've never used it since that one time. i'll use the readout on the loran for headings, distances and the like. otherwise i'll use either my hand held GPS or just the VOR's. but i do cross check every instrument with one another.
