Dynon Certified and the glass cockpit revolution that finally broke the certified aircraft monopoly

Dynon Certified’s SkyView HDX system broke Garmin’s near-monopoly on certified aircraft glass cockpits, offering comparable capability at roughly half the installed price. Since receiving its first STCs in 2018 for the Cessna 172 and Piper PA-28, Dynon has expanded the total glass upgrade market — not just taken share — making modern avionics financially viable for owners and flight schools that had written off panel upgrades entirely.

Why Did Certified Glass Cockpits Cost So Much?

For nearly two decades, Garmin was the only serious option for glass avionics in type-certificated aircraft. The G500, G1000, and later G3X were excellent products, but without competition, prices stayed high: $40,000 to $80,000+ for a full retrofit in a legacy piston airplane.

For an aircraft worth $120,000, that math didn’t work. An entire generation of certified aircraft owners kept flying behind forty-year-old steam gauges while experimental builders enjoyed modern glass panels at a fraction of the cost.

The barrier wasn’t technology. It was regulation. Technical Standard Orders (TSOs) require extensive testing, environmental qualification, and software assurance under DO-178C standards. The FAA certification process is neither fast nor cheap, and it created a moat that only a company with Garmin’s resources could afford to cross.

How Dynon Crossed the Certification Moat

Dynon had already become the dominant avionics provider in the experimental homebuilt market. The SkyView HDX was flying in thousands of RVs, Sonexes, and Zeniths with ten-inch touchscreens, synthetic vision, engine monitoring, and autopilot integration — all for under $10,000.

Rather than pursuing full TSO approval for every component, Dynon used the Supplemental Type Certificate (STC) pathway. This FAA-accepted approach still requires systems to meet the same performance and reliability standards, but provides a more navigable route for companies that aren’t Garmin-sized.

In 2018, Dynon received its first STCs for the certified SkyView HDX in the Cessna 172 and Piper PA-28. The installed price: roughly $20,000 to $25,000 for a ten-inch primary flight display with engine monitoring and backup battery. The comparable Garmin setup ran $40,000 to $50,000 or more.

That’s not a marginal difference. That’s the difference between upgrading and not upgrading.

What Makes the SkyView HDX Competitive?

Dynon’s experimental heritage shaped the product in ways that matter in the cockpit.

Display quality is exceptional. Screen brightness is among the best in the segment — a detail that matters more than any spec sheet feature when reading instruments on a sunny day at 8,000 feet.

Synthetic vision renders terrain, obstacles, and traffic on a display that feels genuinely modern. The system includes built-in angle of attack indication, CO monitoring integration, and a Wi-Fi interface that connects to ForeFlight and other electronic flight bags.

The autopilot integration earned particular praise. Dynon’s two-axis autopilot, proven across thousands of experimental installations, was adapted and certified for the HDX line. Many pilots describe it as more intuitive than the older Garmin and S-Tec units it replaces.

Where Dynon Certified Falls Short

Aircraft coverage remains limited. Each new aircraft model requires a separate STC with its own certification effort. Dynon started with the Cessna 172 S/R models and Piper PA-28 series and has been expanding, but owners of Bonanzas, Mooneys, or Cessna 182s may find their aircraft isn’t covered yet.

The dealer and installer network is smaller. Garmin has spent decades building relationships with avionics shops. Finding a Dynon-experienced installer with the right STCs for your aircraft can be challenging depending on location. Installation quality matters enormously in avionics — a great product poorly installed is a bad product.

High-end feature parity favors Garmin. Flight plan management, approach database coverage, and integration with navigators and transponders benefit from Garmin’s ecosystem advantage. Garmin controls the full stack; Dynon is still building those partnerships.

Vendor longevity is a consideration. Garmin is a $7 billion company. Dynon is private and much smaller. While Dynon has been operating since 2000 and appears financially healthy, avionics installed today may need support for twenty or thirty more years. This isn’t a reason to avoid Dynon — it’s a factor to weigh honestly.

How Dynon Changed the Entire Market

Garmin responded to competition exactly as economic theory predicts. The G3X Touch certified came down in price. STC coverage expanded. The value proposition sharpened.

The data tells the real story: since Dynon entered the certified market, the total number of glass panel upgrades in the legacy piston fleet has increased. Dynon didn’t just take market share — it grew the pie. Owners who had dismissed glass upgrades reconsidered. Some chose Dynon. Some chose Garmin at new lower prices. Either way, more airplanes got modern avionics, and that’s a safety win.

Other competitors are watching too. uAvionix is attacking the low end with the AV-30 series. Avidyne continues pushing their IFD navigator line. The certified avionics market is more competitive in 2026 than it has been in two decades.

Why This Matters Most for Flight Schools

Flight schools operate on thin margins with fleets of twenty- to forty-year-old Cessna 172s and Piper Warriors. Students need glass cockpit experience for airline and modern GA careers, but $60,000 per airplane across a fleet of fifteen trainers is financially devastating.

Dynon Certified changed that equation. Schools can install modern glass panels at a sustainable price point. Students train on real glass avionics. Aircraft become more attractive to renters. Safety improves through synthetic vision, traffic awareness, and engine monitoring instead of steam gauges and a vacuum pump running on borrowed time.

Flight schools that have made the switch report the same results: students and instructors prefer the Dynon panels, and the cost savings allow faster fleet-wide upgrades.

What Buyers Should Know Right Now

If you fly a Cessna 172 or Piper Cherokee, Dynon Certified belongs on your short list. Get quotes from shops experienced with both Dynon and Garmin. Compare the features that matter to your flying — autopilot options, display sizes, and whether Garmin ecosystem integration is important to your mission.

If you fly a different type, check Dynon’s current STC list. Coverage is expanding but may not include your aircraft yet.

If you’re shopping for a used airplane with a Dynon Certified panel already installed, don’t let unfamiliarity cause hesitation. The hardware is proven across tens of thousands of experimental installations, and the certified version adds FAA validation on top of that foundation.

Key Takeaways

• Dynon Certified’s SkyView HDX installs for roughly $20,000–$25,000 versus $40,000–$50,000+ for comparable Garmin systems in supported aircraft
• STC coverage started with the Cessna 172 and Piper PA-28 in 2018 and continues expanding, but not all aircraft types are covered yet
• Dynon’s entry grew the total glass upgrade market, not just its own share — competition drove Garmin to lower prices and expand offerings
• The installer network and ecosystem integration still favor Garmin, but Dynon’s are growing
• Flight schools benefit most from the lower price point, enabling fleet-wide upgrades that were previously unaffordable
