Questions? Contact our support team or call (540) 309-6427. Installation kits are warranted by The STC Group LLC to be free from defects in materials or workmanship for the earlier of 3 years or 400 flight hours from the date of purchase (6 months / 200 flight hours for factory-repaired or overhauled exchange units).

The autopilot control head, servos, and electrical harnesses are manufactured and warranted exclusively by Trio Avionics Corporation, not The STC Group. See the full STC Group warranty terms.
Cessna 170B Vintage Panel Integration & Resources
- Classic Panel Interfacing: Fully compatible with original vintage instrument layouts, traditional steam gauges, or modern electronic flight instruments commonly retrofitted into classic aircraft (including Garmin G5, GI 275, Aspen Evolution, uAvionix AV-30, or Dynon).
- Coupled Approach Precision: Tracks WAAS GPS vertical guidance, including LPV approaches, when paired with a compatible navigator (Garmin 430W/530W, GTN series, Avidyne IFD) to significantly reduce pilot workload in tailwheel environments. The Trio Pro Pilot does not provide coupled ILS approach capability.
