Is this for experimental? How does it pass through the GPS data to the G5 for the GFC failover feature that the certified version requires?
I think the OP was wondering about the connection between the G3X and the GPS 175, not the GFC 500. The G3X has no ARINC 429 interface other than the GAD 29. I don't know the GPS 175, but for example with a GTN 650 I had to use the ARINC 429 to communicate between my G3X panel and the GTN. Maybe the GPS 175 can speak some other language to the G3X than ARINC 429, but my guess is that it doesn't, which necessitates the GAD 29.
It is easier if you can get the install manuals. But they aren’t always easy to find for the certified units. And even if you read them all, there is bound to be a footnote you miss.
Would you visit your local Garmin dealer less often if it were?
Non-TSO, no STC and major alteration? I'm guessing the answer is "no".
I believe dual G3x is single ADAHRS, which is why certified installations require the backup G5.
Looks like that’s the case. Probably it is easier to get the G3X Touch and GFC 500 certified in new types when they are certified separately.
My understanding is you can add an ADAHRS but easier to add a G5
Maybe on the EAB side. I don't see it as an option on the certified side unless something changed recently..
