Does anybody use two ADAHRSs with their G3X Touch system? If so, I'd like to ask a few questions.
Background: in my current RV-10 I have one ADAHRS and one G5. If they ever disagree then I plan to use Foreflight (connected to Sentry) to figure out which is closer to correct. But I'd have to notice that they disagree. In my future RV-10, I like the idea of having two ADAHRSs because I understand that the system can alert you if they disagree. Then I can use the G5 to figure out which is correct. Admittedly a failure mode that produces bad values yet doesn't cause the entire unit to fail seems pretty unlikely.
If you have done this before, here are my questions that I couldn't fully answer by reading the G3X Touch manuals:
1) Does it auto-detect disagreement as I think it does? Have you ever seen this happen?
2) I'm thinking I'd hook each ADAHRS up to a separate static port, but was planning on sharing a single pitot tube and magnetometer -- good idea? Or should I have two pitot tubes?
3) It looks like with two PFDs (pilot, copilot) you can configure each PFD to use a different ADAHRS, but it can fail over. How does that failover work?
