High-End Autopilots

As an airplane owner, I quietly find myself looking at each new device both as an editor and as a potential buyer. Of course, most owners find new gadgets attractive, but when you actually get to try these things out, use them in action, well, I often find it more difficult than others to resist. So, flying these new autopilots in my aircraft type left me wanting one right away even though my autopilot works perfectly. Are you feeling my pain yet? Nah, I didnt think so…

Key Takeaways:

  • The article compares two modern, high-end digital autopilots, the S-TEC 3100 and Garmin GFC 600, for retrofit into high-performance singles and piston twins, highlighting their similar core features and advanced capabilities.
  • The Garmin GFC 600 generally offers tighter control, a "Nanny mode" for envelope protection, coupled missed approach capabilities, and fully implemented VNAV with compatible Garmin navigators.
  • The S-TEC 3100 provides substantial cost savings if upgrading from an existing S-TEC system, as it reuses existing servos.
  • For new installations, the Garmin GFC 600's enhanced features and perceived tighter control might justify its higher price, while the S-TEC 3100 remains a highly capable and cost-effective option, especially for S-TEC owners.

Many pilots think that being an editor or journalist in aviation is a dream job. And, in many ways they’re right. We often get the inside track on FAA activities; we can go to all the shows as part of the job; we fly a lot of GA for business; and we get to play with all the latest toys from the manufacturers.
