We asked Garmin about this requirement and it responded: "Yes, the STC'd G3X Touch does require standbys for an IFR installation like John describes (just like most EFIS/PFD installations). But the good news: A single G5 can take the place of the vacuum attitude, the mechanical airspeed and mechanical altimeter. The G5 attitude instrument is also highly integrated with the G3X Touch. We thought that was a great deal versus having to keep the old iron gyro equipment or install a more expensive electronic standby, like a Mid-Continent Instruments and Avionics MD302, to name one."

Backing up Garmin Glass

I read your review of Garmin’s now STC’d G3X Touch integrated avionics suite in the June 2019 issue of Aviation Consumer and I think you left something out.

I have a 1981 Cessna P210 and would like to install the G3X Touch when it gets on the AML for my plane. If you look at the Garmin G3X Touch website and keep scrolling down they rather casually mention that for IFR you must retain the vacuum-powered attitude indicator or install the Garmin G5 as well.
