Dynon D 10-A with 337

[jjbely]

Hello,

I am now working on the avionic suite for N95803 and I was wondering about the backup AH issue in case of vaccum and electrical failure. I was thinking of installing a certified back-up Mid-Continent AH with battery but there is another instrument made by Dynon that could do the same with battery backup at a lower cost. Could it be installed with a Field Approval as a secondary AI ? It's pretty much self contained and doesn't really need any connection except power. The whole information is coming from the adhars device and the battery should last in excess of two hours. :confused:

If no one has experience with Dynon here--I know their PFDs are used widely in LSA's and experimentals--you could contact the company and ask about installations in regular certified aircraft such a 182. If you find out anything interesting please let us know!

Kevin,

I just did search on their forum and it is a bit of a grey area, some had success and some hadn't with the 337. It looks like the issue is more with the connection to the pitot static system that is needed rather than the electrical connection. I' ll try to get some more information at my end. If you happen to speak to your avionics shop, thanks for asking him his advice.

Cheers,

JJ

We have not been successful getting a field approval for the Dynon equipment in certificated airplanes. I even tried it as passenger entertainment. I visited with a friend in the Aircraft Cert. Office and the FSDO and I don't expect to every get a field approval, althought I've heard, but not seen, some did. The reasoning is the failure modes are unknown, and an "iron" gyro will always show "dirt" or "sky", they never completely disappear.

We have installed the Dynon equipment in a few homebuilt/experimental packages and the customers were very happy.

We prefer the Mid Continent 4300 series gyro for a backup horizon. It's built like a tank, and of course has a battery and internal light. If you add an external battery to some of the others the price ends up similar.

Hi Kent,

Thanks for the input. This alo confirms the recent information I got, I will have to get a Mid continent unit then.

I tried purchasing a dynon and initially they said no. As I fly outside the US with a Non N tail number they were able to ship it. They are fairly common here and you see them in 182, 206, 210, aztecs and barons. They are not used as the primary but the backup gyro.

Thanks Patrick. As I will keep my A/C in the N register , I have to follow all the FAA rules and our local repair station is very strict on implementation. They want to mantain their status and get regular visits fromthe FAA. By the way , where are you located ?
