Certified Autopilot for the Cessna 190 & 195

The Trio Pro Pilot brings a certified two-axis autopilot to the radial-engine Cessna 190, 195 Businessliner, LC-126A, and LC-126B — built to fit a vintage panel without asking you to change what makes these airplanes worth flying.

Before You Decide

A radial-engine classic deserves a panel plan as thoughtful as the restoration itself.

The Cessna 190 and 195 Businessliner occupy a category of their own. Built around a Jacobs or Continental radial engine and carrying real presence on any ramp, these airplanes are flown by owners who chose them deliberately — for fly-ins, for vintage rallies, for the sound and feel of a radial up front, and often as the centerpiece of a long-term restoration.

Owners of these airframes already understand what makes them different: fewer parts suppliers, a smaller community of dedicated mechanics, and a mission that's usually built around getting to a destination that matters — an airshow, a fly-in, a gathering of other Businessliner owners — not just logging hours.

The long transit legs to those destinations are exactly where an autopilot earns its place. A 190 or 195 owner isn't looking to automate the flying experience away. They're looking to arrive at the fly-in less fatigued and ready to enjoy it.

Flying to fly-ins, airshows, and vintage rallies that require longer cross-country legs
Completing a restoration and modernizing the panel to match the work already done
Maintaining an instrument rating for weather flexibility on longer trips
Looking for a certified autopilot option built for a vintage radial-era panel

These are ownership questions from people who already know their airplane well. The Trio Pro Pilot fits a vintage panel, operates with steam gauges, and doesn't require the airplane to be modernized around it.

Are your longest legs the transit flights to fly-ins and airshows, not the arrival itself?
Have you completed a restoration where the panel is the piece that hasn't caught up yet?
Would arriving less fatigued change how much you enjoy the destination once you land?
If weather closes in on a longer trip, would having the airplane hold course and altitude give you more capacity to manage it?
Is a certified, vintage-panel-friendly autopilot the piece that's been missing from your modernization plan?

These questions matter because a 190 or 195 is rarely flown for utility alone. It's flown because the owner loves it. Protecting that experience by reducing fatigue on the transit legs is the whole point.

Special order, built for your airframe Because the 190/195 series spans a range of radial installations and panel configurations, kits for this airframe are special order. Jeff coordinates directly with the manufacturer to build your kit to your specific tail number and panel.

The Trio Pro Pilot works with original steam-gauge panels or with Garmin, Aspen, uAvionix, and Dynon equipment where owners have modernized parts of the panel. It's certified under STC SA04230CH for the 190, 195, LC-126A, and LC-126B.

"The question I usually ask is simple: if this were my airplane and I could only make one major upgrade right now, which upgrade would produce the greatest improvement in capability, workload reduction, safety, and practical utility?" — Jeff Johnson  |  Instrument-rated pilot  |  N1595R, Trio Pro Pilot installed

For a 190 or 195, that answer is almost always about protecting the experience the airplane was bought to deliver — the fly-in, the rally, the destination — by making the transit legs less tiring.

Why this page has two paths If you already know the Trio Pro Pilot is the right fit for your 190 or 195, the product and ordering information is below. Because these are special-order kits, call Jeff directly to start the build process for your specific tail number.

The goal is to help you get the most out of an airplane you've already invested real time and care into — not to push a product onto every radial you see on the ramp.
