Welcome the future into your Citation cockpit

With our carefully engineered avionics and cockpit upgrades, you and your crew will feel like they’re in the newest business jet on the market, but for a fraction of the price. Safety, convenience and up-to-date technology are crucial, and we can give them to you.

As an authorized dealer for all major avionics manufacturers, we can completely update your existing panel to take advantage of 21st century technology.

What’s more, our in-house machine shop offers sophisticated CNC tools, including a state-of-the-art waterjet cutting system, allowing us to create a superbly finished custom-engineered panel for your new avionics suite.

Need troubleshooting for nagging avionics problems? Classic aircraft have typically experienced multiple rounds of avionics replacements and rewiring over the years, often with incomplete documentation. Not to worry. Sierra’s avionics experts have decades of experience in investigating, diagnosing and fixing improperly engineered or documented retrofits. Bring your aircraft to Sierra avionics and our technicians will hunt down and repair those troubling squawks!
