Certified on over 40 legacy aircraft models.
Full-Featured Without the Price Tag
Trio offers altitude hold, GPSS, vertical steering, and other advanced features at a fraction of the cost of competing systems.
Installable by Any A&P with IA
Unlike Garmin, Trio doesn’t require a dealer. Any certified A&P with IA can perform the install—no months-long dealer wait times.
Prebuilt Wiring Harness
Trio ships with a factory-built harness, so your installer doesn’t need to fabricate one. That cuts install time, reduces errors, and saves money.
Complete Installation Kit
Includes most required parts, minimizing time spent sourcing components. That means faster installs, less hassle, and lower labor costs.
Why Choose a Trio Autopilot?
Legendary Customer Support
From pre-purchase guidance to install help and post-sale service, Trio delivers unmatched support—real people, real answers, when you need them most.
Putting Safety-First
Upset Recovery Mode, 180° Turn, Track Offset, and Pilot Command Steering (PCS) provide backup in emergencies and real-world scenarios like disorientation, incapacitation, or weather.
No EFIS Required
Trio includes built-in pitch and roll sensors, so it operates independently with just a GPS signal. Garmin systems require a G5, G3X, or GI 275—and don’t support non-Garmin EFIS.
Certified for Popular GPS & EFIS Units
Trio integrates with Aspen, Garmin G5, Dynon, and soon GI 275 and AV-30C. Use your current setup—no forced avionics upgrades.
Faster Lead Time
Avionics shops are often booked out for months. Trio installs can begin much faster, getting you in the air with less downtime.
