That’s the MD23 Flex 3Pack in the horizontal arrangement. Since these are individual standalone (but interfaceable) instruments, you can mount them in pretty much any configuration that suits the layout.

In the early days of integrated big-screen glass—retrofit and OEM—2 1/4-inch backup flight instruments weren’t uncommon. They save panel real estate (essentially fitting into a round clock cutout), plus high-quality all-electric gyros seemed the perfect complement to Garmin’s G1000 and G2000 suite.

But with many of these instruments at the life stage requiring overhaul, thoughts turn to a more modern backup, while retaining a 2 1/4-inch mounting scheme.
