Another thread in this section got me thinking about IFR panels, partial panels, and backups. I'm very close to building my panel and the timing is good, so I thought I would generate the Q/A session and get some opinions.
I'm planning a dual 10" Skyview screen with single ADAHRS, and either a 430W or GTN650, dual nav/comm. The requirement during training for doing partial panel has me a bit concerned, I'm not sure what pieces/parts of the system are going to be "failed" and I would need backups for. With dual screens I obviously have full backup of all items on either screen, and the single ADAHRS can input data to either screen if one goes down, but I'm guessing in this scenario the DE would get an evil little grin on his face as he failed my single ADAHRS? I was not planning on any round guages for backups - but the more I think about that the more I think a second ADAHRS would be a good idea. Electrically speaking, the screens are good because each will have it's own backup battery so that's not an issue in the event of full ship electrical failure, which is remote occurrence in itself since I'll have main and standby alternators.
Thoughts?
