PT20J Posted February 2, 2022 Report Posted February 2, 2022 One of the advertised new features of v9.00 is adding ARINC 429 labels for fuel quantity and fuel flow so that the GTN will use actual sensor data for the fuel range ring. Other GTN functions may use this data, but the Pilot's Guide isn't very clear. Last week I had G3X v9.00 and GTN v20.23 installed and this isn't working. I verified that GTN ARINC 429 1 input is set to low, EFIS Format 2. Dealer said Garmin didn't specify any configuration change for the feature. Has anyone figured out how to make this work?

PT20J Posted February 4, 2022 Author Report Posted February 4, 2022 From a response I got on Beechtalk, it looks like the shop missed a required change on GTN ARINC 429 1 input to GDU Format 2 when installing v 20.23. I'll try that. 1 Quote
