As discussed in other threads, an error in TAS can make the Dynon wind arrow useless for small magnitude winds. In my A/C with a 4% low TAS indication, it means that I'm always flying with a headwind indication in calm air. So, my opininion is that we in fact do need a TAS calibration table so...

This sounds to me like one of your connector pins is not seated all the way. Check your wiring harness to makes sure all of the D-SUB pins are fully seated. Vern Little, RV9A

In my opinion (and was discussed about a year on airspeed calibration), any static position error or instrument error in the D10A can lead to large variation in the wind arrow. For example, my D10A reads about 4% low in my RV-9A. Therefore, at 100 KTAS (104Kt ground speed) with a 4 knot cross...

Not sure waiting for the Altitude bar fixes the problem. I don't adjust baro setting until after I get the ATIS, by which time the unit is stable. My work around is just to exit the Baro setting page after adjustment. Any rate, it's not a big problem. It was only a problem during formation...

I have found that if I set my Baro on the ground and leave the menu page in place, the VSI bar does not work. I need to exit the setting page then everything works fine. If I set the Baro in flight later on, eveything works fine. Let me know if you need more information. Current software...

Well Dang it! Avmap has a GEOPILOT II + with the video input. It's not the big display like the AVMAP II, but it does replace an additional display for taxi-aid camera systems. Vern

I know that Dynon does not want to develop a GPS Map display because it's a lot of effort just to replicate what GPS manufacturers are expert at. That's too bad, though because I think competitors will make advances on this front, and put Dynon at a disadvantage. Currently, I think the best...

Once of the features that I built into my glareshield AOA display (V-Speed ADS from www.vx-aviation.com) is the ability to provide a FLAPS extended alarm when exceeding Vfe and the flaps are extended. In the spirit of obsoleting my own product (and improving Dynon's), I think it would be very...

Has anyone managed to get Altitude to display on the HSI page when connected to a Garmin 296? I'm running NMEA IN/OUT. Advice appreciated. Vern Little

That's the way I thought you might do it. Drat, now I have to run a wire from the wing. Vern

Can you illuminate me on the characteristics of the heated Pitot/AOA? Does the controller cycle the heating element on and off to maintain temperature, or is it a linear regulator? If it's a linear regulator, what is the minimum current through the element during normal operation? For...

I agree-- Dynon's support has always been very good. This topic has been a good example. The triple net of this discussion is that the correction of TAS is the safest and most useful function. Correcting for static position error sounds more hazardous/error prone (as Kevin discussed)...

Kevin, thanks for the support on this. I knew you'd be on this like a Terrier. I'm sure Dynon is asking "how much more revenue can we generate with this feature". Well, it's an arms race out there... if other EFIS manufacturers implement it first, then Dynon would be at a disadvantage...

I would settle for just TAS calibration and uploading the error table to allow pitot/static adjustments. It would be nice to enter correction factors for IAS, but I understand the inherent problems of mucking with primary flight data. I know you guys aren't looking for creeping features, but...

Now that you can take GPS data for the HSI page, I think it's quite possible for Dynon to have auto calibration for airspeed. For example, one could fly (at least three) headings under screen prompt for the EFIS to determine airspeed errors. This could be done at several indicated airspeeds to...

Previous post should have said "constantly lower readings from the Dynon than the ASI" Vern

Kevin, I didn't do this. Instead, I tapped on the ASI until it stabilized, and compared this reading with the Dynon. The tapping had the effect of giving me the same readings going up as down (in a couple of test cases). It is possible that this has an effect in flight, but I'm seeing...

Actually, when I did the airspeed calibration, I left the pitot open, and applied a vacuum to the static port using the manometer. This should be equivalent. Both agree on the ground, but not in flight. The dynamics of the ASI and the Dynon are different, so it's necessary to be in stable...

I thought this discussion had run it's course, but I now have some new information. After calibrating my D10A and ASI on the ground using a water manometer, I was satisfied that both were accurate within 1% (experimental error). Even though in-flight calibration showed the TAS indication of...

The roadmap from the virtual DG page to the HSI page is welcomed. Those of us with single D10A installations, however, have a bit of an issue... It would be very beneficial to have the DG page also display selected air data (or the primary display show the DG). I realize that there is a lot of...
