It's a bit of an odd critter, but if you buy it with the GPS and backup battery options, it does give a heading (track, actually) indication that's completely independent of your plane's electrical system. It also provides pitch and bank info. Hard to find equivalent info from 2-1/4" instruments without spending a fortune. Jim Cameron Legacy N132X
