My Dynon D-10 EFIS arrived today. It would have arrived several days earlier, but UPS only had my office phone number, and I have been out of the office for several days. It is great to finally have the unit in my hands. I can't wait to get it flying.

I ordered the internal battery option, so I could power the unit up as soon as I pulled it out of the box. It is amazing how quickly the unit powers up. It displays the attitude about 2.5 seconds after power is applied with the unit stationary on a table. It still takes 2.5 seconds if you hold the unit in your hand and move it around slightly as it powers up. The altitude display takes the longest to come on line; it takes about 25 - 30 seconds before it is displayed, at room temperature. I noted one bug - the bank angle pointer is limited to about 65°, even if the actual bank angle is greater than that. I suspect Dynon knows about this one already, but I sent them an e-mail just in case they aren't aware of it.

This photos shows the display with the factory defaults. Each of the various display items can be selected to be displayed, or not displayed. I will definitely select some of the default items OFF to unclutter the display a bit. The voltages (below the airspeed digital readout) and the clock (below the altitude tape) will be switched OFF. The altitude tape will probably be switched OFF too.

I just noted that the heading tape wasn't displayed at the top of the screen. I'll need to look into that tomorrow. Perhaps it is not displayed by default, or perhaps it isn't displayed until you do the calibration routine on the flux valve, or perhaps mine is set up to not display unless the remote flux valve is hooked up, as I ordered that option.



It slipped into the instrument panel nicely, after I spent a few minutes with a needle file tweaking two of the screw holes slightly. I drilled the screw holes myself, so they are likely not quite perfectly positioned. I need to make up a wiring harness for it, order so pitot-static fittings and finish the installation.

The display is shipped with a clear plastic sheet over it to protect if. I'll leave that on there until I am getting ready for the first flight.

I originally planned to have a directional gyro below the attitude indicator. I won't need the DG if the heading display works properly, so I'll likely move the CDI up one spot. If the EFIS proves to be a keeper I'll order a new instrument panel blank and make a new one without the removable panel in the centre, as I won't need to remove the EFIS before doing aerobatics as I intended to do with the electric gyros.
