Keith, I suspect everybody at Dynon is running full throttle this week because of Sun n Fun, so we might not get a long explanation in response to your question. I'll try to shed a little light on Do160 testing in hopes you will come to an understanding... Testing to Do160 requires a fair...

Hi Rodney, I don't have a Sonex and am not Dynon support, but thought I'd throw a word or two in here since there have been no responses. The Sonex isn't much different from any other airplane. It's got ferrous metal pieces like control cables or push-pull tubes that move to make the...

Thank you for the reply. I guess my next train of thought would go toward using instantaneous heading indications compared to GPS track info to provide a method of auto-correcting for ADAHRS drift. This is a project near and dear to me as I've done a fair amount of flying in the region of...

I'll second, er, better make that 'third', this request. The VSI display in its current state is virtually useless. After flying an EFIS D10 I decided I'd burn up some of my limited panel space by installing a 3 1/8" VSI below my EFIS-D100. Take a look at the go-around checklist for just...

I'm going to start this off by saying that I don't work for Dynon and had to pay full price for my EFIS-D100 just like everybody else does. OK, now that's out of the way, on to the meat and potatoes... When I first embarked on this project I was worried about getting the installation right...

Hmmm, so my head scratching can end now. Thanks for the reply. As I read through it I had one of those moments when you go "Doh! I shoulda figured that out!" I'm going to throw one more silly question out in hopes you can do your usual magic and get sense through this concrete between my...

Followup Q?Re D10A - External compass calibration I have a follow up question concerning compass inclination - actually a few questions. These are asked in hopes of improving my understanding, not in response to any problems with my unit. I know the inclination is used in calibration of the...

Re: Dynon Serial to Gray Code Convertor - Setup In Thanks for the reply. I guess it's the speed reader in me that missed the cryptic "EFIS-D100 Format Enable" title in the installation manual. Or maybe it's the old geezer in me who needs glasses... :o

Hi There, It seems my memory is failing me. I was certain I had seen in one of the discussions here the description of the proper settings to be used to make the Dynon-furnished serial-to-graycode convertor work. I've searched and can't find this post so maybe my old brain is playing tricks...

Mel - as a Dynon owner I thank you for this feedback. It's nice to know the whole world doesn't turn upside down. Now if only we could convince Dynon to write a page or so about this in the installation and pilot's manuals we'd be in great shape. ::)

Keith - your point is very valid. I think the next higher layer of reliability comes at a rather astronomical price, like an order of magnitude price delta. That's why I'm happy to live with what the Dynon represents in terms of feature/price tradeoff. I just wish its operating limitations...

Thomas - you hit the nail on the head. Current documentation gives us no idea of EFIS performance in the event of any degradation or failure. Not even if blue is still up and brown is still down. And we don't know how well internal monitoring functions perform in telling us whether a sensor...

Dear Dynon Support, I can accept that answer at face value, sort of. It would be much easier to accept IF the user documentation described these interactions so the user could understand how the box works. As a minimum this info should appear in the installation manual so folks can...

Dear Dynon Support, I fully understand the challenges associated with making the holy grail of AHRS. And I also fully understand that in my price bracket I'm NOT going to get that level of perfection. As such I've got no complaints about the solution which Dynon has chosen to implement (gee...

Dear DynonSupport, Thanks for the update. It's encouraging to know that at least the "bug" is not only understood but also is fixed. Now I'm just more curious to know when the code will become available... ;D One point to note... I work in the high-tech world and too often see projected...

Dear DynonSupport, While I understand you may not be able to give exact dates, would you be able to provide at least some guidance as to what phase of development this Lowrance-compatible load of code is now in? Is it still a lab rat, or is it ready for Beta, or half way through Beta, or still...

Dear Dynon Support, Bingo, you've hit the nail on the head! You've stated that you need a DG with almost zero drift to make this work. The reality is that virtually all light aircraft currently operating within the region of compass unreliability are currently using their cheapo panel-mounted...

Re: UTC and local time differ by 30 minutes There are other places in the world with a 30-minute time zone too. Newfoundland, Canada for example. I'm surprised this fact would escape the manufacturer, but since this code is written in the US by Americans, and since there are no 30-minute...

Likewise - let's twist! ;-) Having been involved in avionics development for many years and can honestly say that twist knobs are vastly superior to buttons for slewing pointers and setting values. Human factors analysis shows that in a high-workload cockpit the crew doesn't have time to hold...

Check my earlier reply concerning "grid" functionality. This effectively answers the question you've asked here. And yes, I still find it hard to believe that pioneering arctic aviators managed to survive flying over such inhospitable lands with so little in terms of navigation equipment. Of...
