7" vs 10" EFIS Primary Flight Display

[BobTurner]

I'm with Larry, in the minority. I have a standard sized GRT HX for PFD or PFD/map; a second GRT HS for engine instruments. I wear progressive lenses and am 20/200 (near vision) without them. I am short so fairly close to the panel. I can read everything without difficulty, so I'll be saving my money for gas (and ADSB-out).

The reality is the market already decided (that meaning the preponderance of people buying EFISes), and by a very large margin choose 10" over 7" or other random sizes (bigger or smaller). Firstly, they fit nicely into most planes and Secondly the costs are similar. That said, there are instances where the smaller one's work better in some aircraft or for a back seat.

In the end, by far and away the 10" size area seems to be the 'GoldiLocks' of EFISes. Some will choose hotter or colder porridge, but as a whole that is the inarguable definitive sweet spot.

Just my 2 cents as usual!

Cheers,
Stein

I think you've got it right Stein - my view is "what fits best in the particular panel, and bigger is better". We have two big Skyviews and one small one in our new Tundra, and when I put the same pages up on the big and little screen, side-by-side, I can tell you I sure wouldn't want to give up the big one. However, for a small panel, I'd rather have a couple of small ones than one big one that allows nothing else in the panel. We've got quite a variety of systems in our planes right now, but generally I want the biggest screen that fits well with redundancy.

The RV-3 fits two old-style G3X displays side by side, the RV-8 lives nicely with the original GRT HX's - but the RV-6 really works nice with one large G3 Touch in front of the pilot and a small G3 Toush in front of the right side. Teh Tudnra's panel is very roomy, so both seats get a big Skyview and share the small Skyview in the middle.

The Goldilocks point depends on the airplane!

Hey, we coudl do this as a forum topic!
