Garmin G5 DG/EHSI: Low Cost, STC Limited

As a follow-on product to the STCd G5 electronic attitude indicator, Garmins G5 electronic directional indicator is taking sizable criticism because the instrument doesnt interface with autopilots. While Garmin says this is a temporary limitation, its easy to understand the backlash. After all, the G5 EHSI is intended to replace mechanical, vacuum-driven DGs-many of which work with the heading channel on a variety of existing autopilots. But looking to the future-as in the coming months-there's a bigger story here.
