    D1's first "Save"

    Last week, my friend flew his Mooney from FL, to NY to help me with work. (By the way, I urged him to purchase a new vacuum pump, which he did, but he did not install it) On descent, having just popped out of hard IFR conditions, he changed RPM and his vacuum pump failed. He was certainly happy...

    Skyview 10 inch, video input needed !!

    About 2 years ago, I vaguely remember discussing a video input option for the Skyview system. I remember being told that it was possible and that it's probably coming. Well, I need it. I have installed the 10 inch Skyview in our experimental exhibition Extra 300L. Because it's a taildragger...

    Side-mount heated AOA pitot?

    Please see our thread on the static ports/pitot. http://dynonavionics.com/cgi-bin/yabb2/YaBB.pl?num=1324940479

    Static ports located on Pitot/AOA probe

    Here is a pic of the pitot tube used in the above graph. Interestingly enough, it's not that different from the original one on our Extra 300L. I spoke with Dynon customer service about this, and the distinct impression I came away with is "why?". I'd like to explain my position. It's my...

    Static ports located on Pitot/AOA probe

    It might help to have a few pics to look at:

    Static ports located on Pitot/AOA probe

    If, the 3 layers are too much, and 2, not enough, what is the "perfect dimension" of the "ring"? In the case of our Extra 300L, the pitot tube has an extension on it and is farther from the wing leading edge than the MX-2 with similar setup. Yet, I believe we are seeing similar issues. A...

    Static ports located on Pitot/AOA probe

    No autopilot yet, so that's out. I'll fly the GPS box or triangle sometime soon. Looking for a day with light winds... Of course, the airspeed information is heavily biased towards pitot pressure. Slight differences in static information will make very small changes in indicated airspeed. In...

    Static ports located on Pitot/AOA probe

    Good Afternoon all, I modified a straight Dynon Pitot/AOA probe to include static information. I did this by drilling a ring of 12 small holes, at 30 degree intervals, about 30mm distance back from the tip. I then removed the silicone sealant from the inside of the tube. I installed another...

    Fuel flow "red cube" and "flowscan" options gone

    OK, thanks that makes sense. I'll come up with some other way to calibrate the unit. Probably the beaker and stopwatch method. Using simple trial and error and some high tech reverse calculations :D . I'm sure it will be close enough.

    Ok, thanks, I'll bump this thread next year.

    Fuel flow "red cube" and "flowscan" options gone

    Hi there! This past summer, I installed a SV system and selected option other than the "red cube". It seemed to work fine. After replacement of the Dynon SV, the option is not there, so I set the unit for 29,600 pulses per gallon (I believe I have the number correct). Clearly, that's not...

    GRT map sensor ??

    GRT sent me an email with the following: "For every 1 volt change in the output of the map sensor, this corresponds to a change in manifold pressure of 5.64 inches of Hg. You need to add 4.3 inches of Hg to the conversion (that is, with 0V output, the sensor is indicating 4.3 in Hg) This...

    TIS traffic red X

    Thanks for the info! Suddenly, the system works just fine.

    In addition, is there a list or a map of where TIS service is available?
