Q: What do I need to have to install this autopilot?
A: The only external equipment you will need is a GPS to drive the Trio Pro Pilot autopilot. For approved GPS models see the Avionics Compatibility List under the Resources->Documents tab.
Q: How does the Trio Pro Pilot autopilot work?
A: This autopilot uses digital inputs from a panel mounted or portable GPS for navigation functions and taps into the pitot/static system for altitude and airspeed information.
Q: Does the autopilot fly ILS approaches?
A: No, but it will follow any GPS approach overlay if you have a WAAS navigator installed.
Q: Will this autopilot work with Non-WAAS GPS?
A: Yes, with a Non-WAAS GPS the only functionality you will not have is vertical guidance for approaches. IFR related procedures (GPS approaches, procedure turns, holding patterns, etc)
Q: Will it interface with any PFDs? (Garmin, Aspen, Etc.)
A: We are currently in Flight Testing for new software that takes inputs from Garmin G5 and Aspen EFD E5 and EFD1000 systems.
Q: Is the autopilot approach certified? Does it need to be disabled at 500 feet AGL?
A: The autopilot will perform bendover and track the descent profile on LPV/RNAV approaches but must be disengaged at 500 feet AGL.
Q: Do you have an EASA STC?
A: Currently we only have an FAA STC but contact customer support for more information on EASA installations.
Q: What else will I need to complete the installation of this autopilot?
A: The only items that do not come in the kits are pitot/static tubing and hardware. The pitot and static ports on the autopilot utilize 1/4” ID and 3/8” OD Tygon style connections.
