Trio Pro Pilot  ·  Exclusive Authorized Source

Your Aircraft Can Do More.
So Can You.

Most pilots fly without an autopilot not because they don't want one — but because they don't know if it's right for their aircraft, their panel, or their budget. That's exactly what this is for.

The Honest Comparison

Garmin makes excellent autopilots.
They're also about twice the price.

The GFC 500 is a capable system — but it requires a certified Garmin EFIS, a Garmin GPS, and a Garmin-authorized installer before it flies. The Trio does the same job on approaches, works with your existing panel, and installs with any A&P/IA. We lay out the full breakdown — sourced pricing, the EFIS requirement, the Bendix King Aerocruze 100 — honestly, side by side.

Trio: no EFIS required
Trio: any GPS, any A&P/IA
Trio installed: $11,000–$14,000 all in

Who Answers the Phone

Not a sales desk.
A pilot who flies this system.

Jeff Johnson is an instrument-rated Grumman Tiger owner. N1595R has a Trio Pro Pilot installed, paired with dual uAvionix AV-30C units and a Garmin GNS430W. He flies IFR with it. He's flown coupled GPS approaches with it in actual IMC.

When you call TrioAutopilots.com, you talk to Jeff. He reviews your aircraft, your panel configuration, and your mission before making any recommendation. No call centers. No dealer queues. No one reading from a spec sheet.

That's not a marketing line. It's just how this works.

Before You Call
Straight Answers to the Questions Pilots Ask First
Does the Trio require an EFIS or glass panel?
No. It has built-in pitch and roll sensors and works with standard steam gauges — no G5, GI 275, or any electronic flight instrument needed to operate it. That's a core difference from the Garmin GFC 500, which can't function without a certified Garmin EFIS. See the full comparison →
How much does it cost installed?
Typically $11,000–$14,000 all in, including about 40 hours of installation labor at prevailing A&P/IA rates — with no required EFIS or brand-specific GPS to add on top. A consultation gives you a realistic number for your specific aircraft. Request a consultation →
Are there ongoing subscription or data fees?
None. The Trio Pro Pilot is a one-time purchase — no subscriptions, no data fees, no recurring charges of any kind.
Can any mechanic install it?
Yes — any A&P with an IA can install it under STC SA04230CH. No dealer certification or factory-authorized installer required, so you schedule with your own trusted shop. About installation →
Will it work with the GPS I already have?
In most cases, yes — Garmin, Avidyne, Dynon, Aspen, iFly and others are supported. For VFR modes even a portable GPS qualifies; full IFR approaches need a compatible certified navigator, but it doesn't have to be a Garmin. If you already own an IFR GPS, you're likely set. GPS compatibility →
Is my aircraft covered by the STC?
The STC covers a wide range of Cessna, Grumman AA-5, and Piper PA-24, PA-28, and PA-32 models. The fastest way to confirm your exact model and serial number is a quick compatibility check. Check compatibility →
