Sport EX using Trutrak autopilot

Postby pilotmansam » Wed Jun 19, 2019 9:37 pm

I have installed a Sport EX and interfaced this to my Trutrak Vizion autopilot. This all seems to work great and is very enjoyable to fly. I am considering purchase of the GRT ARINC module. My first question is, if I connect the ARNIC to the EFIS and to the autopilot, will the EFIS send vertical and lateral guidance via the Synthetic Approach to the autopilot? This would be fun to experiment with!

If the EX has the Vertical Autopilot Functions option (also known as the GPSV option or IFR autopilot option) then it will send lateral and vertical commands through the ARINC-429 output for all approaches it can capture including Synthetic Approach. If the EX doesn't have the Vertical option then you will only get lateral commands and altitude hold. TruTrak autopilots with ARINC-429 and GPS steering will follow the commands.
