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...

I mounted my EDC in the aft fuselage of my RV-9A slider. After calibration on the ground using a compass rose, I had significant errors in flight. I turned out that when calibrating, my canopy was open. The steel frame of the canopy rolled right back over the EDC location and caused magnetic...

Steve (& others): even though this is a product that Dynon may be working on, Vx Aviation has production released an external glareshield mount AoA display. More information is available at www.vx-aviation.com Thanks, Vern Little
