    Altitude and Airspeed errors

    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...

    Altitude and Airspeed errors

    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...

    2006 Oshkosh Announcements

    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...

    D10 EDC Accuracy?

    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...

    external AOA annunciator possibility?

    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
