You're Talking to the Right People.
Let's Figure Out Who That Is.
Three different questions. Three different answers. Pick your path below — we'll make sure you land in the right place.
Most questions fall into one of three categories. Pick the one that matches where you are.
I'm Evaluating or Planning a Purchase
Researching compatibility, comparing options, or planning a panel upgrade. This starts with Jeff — the only authorized source for the Trio Pro Pilot.
Talk to Jeff ↓I Own a Trio and Need Help
Post-installation settings, operational questions, or warranty issues. Purchased through this site — start with Jeff. Purchased elsewhere — AJ at The STC Group has you covered.
Go to Support ↓I'm an A&P / IA or Avionics Shop
Installation technical questions go to AJ at The STC Group. If you're also interested in receiving qualified, fully-scoped Trio customers — mention that in your message.
Contact AJ ↓There is exactly one authorized source for the Trio Pro Pilot in certificated aircraft. You're already here. No dealer queues, no call centers, no runaround.
Jeff owns and flies a Grumman Tiger IFR with a Trio installed. The advice you get comes from someone who uses this system in actual IMC — not a sales rep reading a spec sheet.
Post-sale technical support routes directly to The STC Group — the entity that holds STC SA04230CH and supports the system at the manufacturer level.
Compatibility reviews, panel planning, and support for systems purchased through TrioAutopilots.com. This is where the conversation starts.
