I'm just finishing up my instrument training, getting ready to take my practical, and I'm trying to diagnose a problem with coupled approaches.
My equipment is full Dynon Skyview Classic, with the ARINC-429 being fed from a Garmin 430W. It works absolutely great for coupled approaches on the RNAV (GPS) side, and when I move the Skyview HSI source to the 430W NAV side I can see the ILS glideslope just fine, BUT the ILS course is always set to 150 degrees and the autopilot will try to turn to 150 degrees regardless of what the actual ILS course is. I have to use the localizer display on the 430W itself and the glideslope display on the Skyview HSI to hand-fly the ILS.
What am I missing here? How do I get the 430W to adjust the Skyview HSI (and autopilot commands) to the correct heading on the localizer? It will lock on and follow the localizer just fine in GPS mode - but NAV mode always brings it to 150 degrees. I'm suspicious this is a configuration problem since 150 degrees is the default test heading put out by the 430W on power-up self-test, but I've been unable to find a configuration problem so far. As a troubleshooting point, I know that the "bearing source" displayed on Skyview HSI will correctly show direction to VOR's being received on the 430W, so I know the connection between the NAV side of the 430W and the ARINC appears good. So far I've been doing this with the autopilot in heading control and NAV armed to capture, and when it captures it just obediently follows the HSI and turns to 150 degrees regardless of the actual localizer direction.
Any ideas?
