While all eyes were on TruTrak and Trio this past year (both were knee-deep in earning STCs for experimental autopilots), Garmin was quietly working on its own retrofit autopilot. Actually, the company already had two: the one that’s integrated within the G3X experimental avionics suite, plus the impressive GFC700 that’s built into the G1000 and G3000 integrated avionics.
The technology in these systems ultimately trickled down to two retrofit autopilots—the entry-level GFC500 and higher-end, clean-sheet GFC600—both of which currently have limited STCs for aftermarket retrofit, but more are in the works. We recently flew with both of them during a visit to Garmin’s flight ops in Olathe, Kansas. Here’s a flight report.
