None of which will protect you from a common mode failure so that is why it is still a good idea to install an independent backup solution with a different hardware/software base.
Define a common mode failure that has occurred in the past please.

I hear this a lot and put Dynon backup in my Garmin panel....but it seems useless to me. Kinda wish I hadn't bothered.

Why?

Such a layout is typically required for real 2 crew operations in the airlines, chartered world (twin turbo props, etc.) and so on ... Do you have a need for your right seater to have everything identical to you? Do you typically fly with a significant other that is als a pilot maybe?

Just curious ... that's a lot of money and weight and complexity ... I'm wondering what leads you to choosing this setup.

Sure looks gorgeous though! Is that the mid-continent stand-by instrument also? So the G3X do not have dual ADAHARS/batrteries, etc?
Why? Short answer is because I can. It's our company demonstrator aircraft. Also, my wife loves to fly, and use the controls on the right side. She's not a pilot yet, but will be working on it shortly. In the mean time, she does most of the squak codes, frequency and baro changes.

As far as weight goes, it wasn't a significant change from the original steam gauge panel.

Yes, it is the Mid-Continent SAM. The left screen (GDU370) has a backup battery that powers that and the #1 AHRS (GSU73). The Middle screen has its own backup battery which also powers AHRS 2 (GSU25). I also have a #3 AHRS, another GSU25. The SAM is there to alleviate the very, very unlikely possibility of a common software problem between the three screens.

Thanks, we designed and 3D printed that in house.

Nice looking panel

What is the small back up unit immediately to the right of the key switch?
It's a Mid Continent MD302 Standby Attitude module, or SAM. It's a great piece of equipment that has some neat features, including automatically adjusting the Baro setting when it's changed on the G3X.

A very general description for this would be "A piece of data that is either incorrectly transmitted to or misinterpreted by the displays that could cause a reset, or continuous reset condition."

I think the likelihood of this actually happening is almost nonexistent. I've got about 300 hours behind G3X systems (Legacy and Touch) and have never had a screen failure.

"It's our company demonstrator aircraft."

Ah, well that makes sense indeed ... cudos to you then! Great panel ... It certainly appeals to the toy loving man in me ... I'll never build out such a panel of course, since I'll never need that much functionality ... but like you said, if you can and want to (And even need to in terms of promotion for the company), why not?

All backups seem useless until you need them.

I don't look at mine either 98% of the time but I will sure be glad to know it is there and working if I am IMC and the G3X system goes South.

One thing I have learned by being so involved in experimental avionics over the past several years is that none of them are perfect and that there is no way I am trusting my life to any one of them.

I am pretty sure that all of the major players in the experimental EFIS market right now recommend independent backups. I thought it was good enough advice to follow and since full blown independent EFIS backups are so economical these days, it just makes good sense to put one in if you are planning on flying in IMC.

$9k for a backup in a RV-7 doesn't make sense to me, I think that's what the mid continent unit runs

I'd like to see a better place for the AP panel but given the layout I don't know what I'd change to make room for it, it's a head scratcher


edit: i've had software issues in both Garmin (G600) and Dynon (skyview) panels compromise the whole system from my pilots perspective, I always advocate backups for reasons like this.
