Pro Pilot Autopilot by Trio Avionics

The Pro Pilot is a two axis autopilot designed for precise navigation and altitude control.  It encompasses all of the performance and safety features of our other systems, and makes them available in a single, panel mounted instrument.  The system includes back-lighted buttons and illuminated face plate nomenclature as part of a pleasing new industrial design.

The Pro Pilot provides excellent horizontal navigation capabilities and the vertical navigation provides altitude control, climb/descent functions with airspeed limiting, and altitude pre-select.  Climb/descent on airspeed is also included.

The Pro Pilot uses Trio's proven "intelligent" Gold Standard servos to assure safe and reliable control actuation.

While the Pro Pilot incorporates many features, it is very simple to operate.  Just press the H NAV button and it will track your flight plan.  Press the V NAV button and it will hold your current altitude.

The Pro Pilot is available in two models - instrument mount and rack mount.  Both models feature backlit nomenclature and bright LED indicators

GPSS (GPS Steering): 

This option might be desired if your GPS receiver or EFIS system provides GPSS commands, usually via an ARINC 429 data output.  In this case, the Pro Pilot will no longer rely upon its own navigation functions, but will follow the roll commands coming from the GPS or EFIS for guidance. 

Note:  If you will be using a handheld GPS to provide signals to the autopilot, it does not have ARINC 429 outputs available

GPSV (GPS Vertical Steering): 

With WAAS approaches coming into widespread use, it is now possible to do precision approaches using approved GPS systems.  The GPSV option allows the Pro Pilot to follow the pitch steering commands that are provided by an approved panel mounted WAAS GPS receiver or EFIS system for descents into an airport. 

The GPSV option requires that the GPSS option is also installed.

The GPSV feature also allows the autopilot to follow the vertical bug on a compatible EFIS system.
