EAA announcement. A few bush planes on the list...

If your aircraft wasn’t among the the first wave of Cessna and Piper models approved for installation under EAA’s Dynon STC, we have great news: EAA just received an expanded Approved Model List (AML) from the FAA. The aircraft models that may now have a Dynon EFIS installed are:

Beechcraft Bonanza / Debonair
Beechcraft Musketeer / Sundowner / Sierra
Beechcraft Skipper

Cessna 150/152 - Commuter / Commuter II / Aerobat
Cessna 172 - Skyhawk
Cessna 175 - Skylark
Cessna 177 - Cardinal
Cessna 180/185
Cessna 182 - Skylane
Cessna 205 / 206 / 207
Cessna 210

Grumman AA-1/AA-5 - Yankee / Tiger

Piper PA-24 - Comanche
Piper PA-32 - Cherokee Six / Lance / Saratoga
Piper PA-28 - Cherokee / Warrior / Archer / Dakota
Piper PA-38 - Tomahawk

Mooney M20

Maule M-4/5/6/7

This is great new. I'm curious what all the EFIS can replace? Is it just the artificial horizon? Or can it replace more?

So far just the horizon, it is not (yet?) certified to replace the DG. It at least gets you half of the way towards a vacuum-free airplane, though.

Ya that's nice for sure. Wonder if they'll ever be able to replace the airspeed and altitude?

One added benefit is that these instruments are self lighted, or the need/reliance on post lights is lessened.

FWIW the approved devices are the Dynon EFIS-D10A (4") and the EFIS-D100 (7").
Looks they are only approved as a primary replacement for the attitude indicator.
