In the parts pile, I have a GMU-22 magnetometer, three GSU-25 ADAHRS units and two GDU-460 displays. I will likely only install two of the ADAHRS units.
I plan to buy a G5 and a GTN-750Xi (to replace a GTN-650 I already have). Am I correct in my understanding that a single GMU-22 can drive both GSU-25's, but not via the CAN bus? If so, will the G5 be able to source magnetic heading information from the GMU-22 via the two GSU-25 ADAHRS units?
If all of the above is accurate, it seems the weak link is the single GMU-22. How likely is a GMU-22 failure?
Is it possible to have a GMU-11 on the CAN bus in the above configuration? If so, what is to be gained or lost in choosing to install the additional magnetometer vs. staying with only the GMU-22?
I'm not trying to design Boeing level redundancy. I'm just trying to get an better understanding of how all of these devices interact and share information.
Thanks.
