Want my steam... yeah yeah extreme improbable situation and a bit untidy but

I have no problem with backups, even steam. However, I don’t like single points of failure.  Can you shoot an approach if you pfd goes down?  What if the display on the 440 goes down?  The dynon backup AI is not able to display course deviation or glide slope as far as I know. 
 

Another option is to go with two G5’s, the 375, and the gfc autopilot. It would allow keeping the panel stock for now and when your ready for the g3x you’ll only loose a couple hundred on the g5 HSI when you flip it.

Copy yes some good points.  I'm thinking if total electrical failure or fire the steam might give me enough to keep control and find clear land.  Dynon backup required with Skyview HDX 10.6" I believe.  If could put a G5 in place legally i would go that for sure.  Anyone with more info on this...
