    Pictures from Arlington

    Banging buttons? They were are lovingly pressed. I went through the entire combination of pages to get an idea of the operation, and Kirk didn't even notice. In all fairness, I hosted Dynon at the Langley fly-in, so I think Kirk trusted me not to destroy anything. BTW, I did a pretty good...

    ADAHRS....

    A closer look at a tandem setup would best put the AHARS in the aft fuselage, perhaps on the tail deck under the VS. All other stations have large current-carrying wires (baggage compartment/battery compartment) or moving hunks of steel (pushrod ends) or are inaccessible. The tail deck...

    ADAHRS....

    Thanks! This information, plus the requirement of twisting the DSAB wires gives us everything we need to prewire. I presume 22 AWG is acceptable. Aft fuselage it is. This works out because we can tee the pitot/aoa where it enters the fuselage and run fore and aft. So we need a 9-pin...

    D11?

    It seems pretty obvious to me that the D10A will never go away due to it's compactness and cost. Even with the next-gen displays, the D10A makes a pretty good backup. The issue(s) at hand are incompatible DSABs, the need to route static/pitot/aoa to the back of the instrument and a remote...

    ADAHRS....

    In a typical installation (all nextgen Dynon), the pitot/static/aoa could be routed to one location (wing tip or aft fuse makes sense). However, if there are any instruments on the panel that require them (such as a backup D10A), alternate static source or mechanical instruments, this requires...

    ADAHRS....

    A question about the ADAHRS. Typically, one would mount this in a magnetically quiet environment, such as the wingtip or aft fuselage. However, Dynon wants pitot/static/aoa connections to the ADAHRS, so that requires routing these lines to the unit.  This limits the flexibility of installation...

    tail dragger option

    I second the motion. A direct video input (or even an external video to usb converter) would be valuable. It would certainly reduce panel space compared to a seperate display. Vern

    Flaps extended alarm

    I actually developed a flaps extended alarm using the D10A. It sniffs the serial output and uses a limit switch on the flaps to generate an audio alarm when greater than Vfe. I've been flying with it for a couple of years. It was never taken to market because the proper place to do this is in...

    AOA Calibration

    David, try checking for a blocked AoA line. Vern

    Airdata accuracy

    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...

    distortion when listening to HS23 warnings

    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

    Wind Arrow Accuracy

    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...

    Minor Bug Report-- Baro Setting & VSI

    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...

    Minor Bug Report-- Baro Setting & VSI

    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...

    Product/Feature wish list

    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

    Product/Feature wish list

    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...

    Suggestion for EFIS feature

    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...

    Dynon GPS Support

    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

    Heated Pitot Install

    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...
