Had a full Skyview system in an RV6. Am considering a D3 for my current plane (Commander 112) but would like to flush mount it in the panel if that would work. I know the D3 needs a GPS signal for airspeed and altitude and was wondering if anyone has tried mounting the D3 where the front of the D3 is flush with the face of the panel, and if so, if there was any problem with it pulling in a GPS signal. I know it would be somewhat unique to the installation and the particular airplane. Just wondering if someone has tried it. Thanks.

You realize the D3 is not approved for permanent mount in certified aircraft, right?
As for reception, there's no way to know without trying it. Every aircraft is different. And since this technically isn't legal for a Commander, I doubt anyone has done it before. You could try just sticking it up behind the panel temporarily, and see if that works.
And for yet another question, you know it can use an external GPS antenna, right?

Good point about the permanent mount, but if you're just using it as an emergency backup does that still matter? Maybe I'll just use the snap in surface mount that it comes with. I did call Dynon and they said that it came with an external antenna.

To the FAA, apparently yes. To anyone with common sense? No.
You can shorten the clip mount so it fits more flush with the panel. There's a thread about that here somewhere, because I helped someone design such a thing. Pretty sure that was to make it fit in a circular opening though.

Found it.

That was to make it fit a round hole, not to shorten the mount. But if you look at the picture of the cradle, you'll see it can be mounted directly to the panel. Unfortunately, at least some of the cable connections come out the sides. I'm guessing that's why you wanted to flush mount it, other than simple aesthetics.
D3 fit to panel with 2-1/4" (57mm dia.) hole, not 80mm ?
Is this possible ? It does not have to be concentric with existing hole. Has anyone done this, perhaps by modifying the 3-1/8" pinch mount or the cradle ?

I was considering it for aesthetics. Wasn't even aware that some of the cables came out the sides. I was thinking of ordering it tonight as their Airventure sale ends today. I did look at the thread that you attached. I'm sure the concept that you had drawn up will work. I may try to design a flush mount where the D3 can still be removed from the front (aft side of the panel) without the use of tools. I could make a good argument that it was not permanent. Thanks for your guidance>

For your consideration, there is a policy statement that allows for the permanent installation of PED (portable electronic device) mounting hardware in certificated aircraft as a minor alteration requiring only a logbook entry.

So that's for the iPad crowd, I suppose.

Scott, I have a D3 in my RV as a backup to my HDX (along with an Aera 660 GPS). There is an external GPS Antenna that plugs in the side, next to the USB power plug. I put the antenna on the top of my glair shield.
Since you want to mount the D3 in the panel of your 112, you can fabricate your own flush mount panel, as long as you can remove the D3 without tools, it is not permanently mounted. Just make a "hat" section out of aluminum to flush mount D3, and Velcro the thing in place and you should be "legal".
The reason I like the D3 for a backup unit is that it doesn't tie into the ship's pitot or static systems. Should ether of those two lines lines get compromised, the D3 should not be impacted. Between the D3 and the 660, should my Garmin 175 or SkyView both die at the same time, I can aviate and navigate with those two things.

Creating a recess in the panel would be a simple thing, if you're willing to put it the work. But if you're really into the aesthetics, I'd make a bezel that pops in over it so you don't see the mount around the D3. Not as pretty as a true flush mount, but it looks better than seeing the D3 mount.
