Dynon Certified Announces SkyView HDX Compatibility with Trio Pro Pilot Autopilot

We are excited to announce FAA approved compatibility of the Trio Pro Pilot Autopilot with Dynon Certified SkyView HDX systems. This integration allows even more pilots the ability to pair a new SkyView HDX avionics upgrade with an approach-capable, two-axis autopilot in their type certificated aircraft.

Dynon / Trio Autopilot Compatibility and Capability Highlights

  • FAA Approved Integration: With Trio’s recent approval, Dynon SkyView HDX may be connected to the Trio Pro Pilot autopilot system, allowing it to follow guidance from SkyView HDX and connected external GPS navigators.

  • Approach-Capable Autopilot: When a compatible IFR GPS Navigator is installed, the Trio Pro Pilot can fly fully coupled approaches.

  • Full Trio Aircraft Model Line Coverage: This approval includes all type certificated aircraft models the Trio Pro Pilot is available for, adding dozens of models that can now benefit from installing a Trio Pro Pilot Autopilot alongside SkyView HDX.

FAA Approved Integration Features

When connected to a Trio Pro Pilot autopilot, SkyView HDX can serve as a single-entry point for heading, barometric altitude, and altitude pre-select. The configurable “bugs” that pilots set on their SkyView HDX system are automatically sent to the Trio Pro Pilot, allowing it to fly the guidance directly provided from SkyView HDX. 

Additionally, when a compatible IFR GPS navigator is installed, the Trio Pro Pilot and Dynon SkyView HDX combine to provide full GPSS course guidance and auto-sensing for autopilot course and descent guidance during RNAV approaches.
