Upgrade to IFR Garmin driving GRT
I am planning to upgrade my VFR RV-7 to bare bones IFR using my GRT HXr and WS EFIS combo. I plan to get a GNC 355 (comm/GPS) to replace my SL-40 and have a great shop to do it for me. My question is whether you think that the WS on the passenger side is adequate for a back up attitude indicator or should go with a dissimilar G5 to replace a mechanical attitude indicator that I have next to the pilot EFIS. With a G5, I wouldn't have a nav connection to the 355 without a lot more expense. It would be attitude, altitude and airspeed but enough for me to keep it right side up if I had an EFIS failure. Although, I could connect my new Aera 760 for lateral nav.
I wouldn't be doing a lot of IFR flying in it but understand that there is no such thing as light IFR. I do the majority of my IFR flying in other aircraft.
Thanks for any thoughts or suggestions.
