What happens when one of your ADHRS’s  starts giving false information and one screen says turn left and the other says turn right? That’s why all FAA certified EFIS systems need 2 ADHRS/displays and a third attitude reference as a tie breaker. Do yourself a favor and install one.

I just have completed the install of a 2 screen Dynon Skyview system with ap and Dynon txpd with traffic, Garmin SL30 radio to give ILS presentation on the Dynon screen.  I have no steam gage backups.  With dual screens, backup batteries and dual ADHRS I feel that I have enough redundancy.  Does anyone have input or comment?  This plane may be one of the first with no round gauges anywhere.
