AOA in the RV-12 - Page 15

I haven't read of anyone trying that. But I bet it would. Aren't most combo pitot/AOA probes simply a pitot pointing forward and another pitot pointing down 30 degrees from that? That's all the inflation needle mod is doing. Certainly easy to test.

I just finished my 12 ELSA and am considering installing the AOA. Can some one post or show me a link to a series of photos of all of the steps including the in / on wing installation?

I'm doing the same thing. Here's the thread I started with. http://www.vansairforce.com/communit...t=homemade+aoa

Ben Barron, this is the thread, start back on page 2. Eventually you'll get to the McMaster-Carr parts list. Leave a little slack at the wing root for the quick disconnect, it comes out through the panel with the wing electrical connectors. You can just lay that 1/8 tubing in the lightening holes if you wing is Already built, fish it through to the stall switch cover plate area with a stick.

I installed the AOA tubing and calibrated it this morning. Almost everything works great: the visual indicator showed up, the calibration went smoothly, and I nailed the first landing. The only problem is that I'm not getting the audible alerts.

I set the relative volume to 100% and I set the trigger level to "middle of the yellow" but even when it gets into the red, I don't hear anything. Other Dynon audible alerts are loud and clear.

Am I missing a setting somewhere? Anyone else have this problem?

Ken, do you have the D180 or the Skyview?
The D180 does mention the Alarm Setup....page 9-31 of the D180 Installation Guide. It shows five audio positions,
Always off,
On in Red,
Start Ylw Top,
Start Ylw Mid,
Start Ylw Btm.
You get to the setup screen by EFIS>Setup>AOAALM

If you have Skyview, it must be something of the same.

Thanks Steve,

I have the Skyview system. As far as I can tell, with Skyview the relevant settings are relative volume (which I have set at 100%) and starting point (middle of yellow).

Still not sure why I'm not hearing anything....

Thanks again.

Ken, I hear the AOA great but not the other dynon alerts. Also my flightcom 103 isolates ME, not the passenger! Your serial number indicates you may be one of us that had to deal with the skyview conversion harnesses? There are issues like this that many of us are experiencing and we haven't figured out yet.

Also, it could be the setting of one of those potentiometers on the AV5000

Ken, did you ever resolve this. I'm having exactly the same problem - everything working great except no AOA audio. Can hear all other warnings OK. I'm getting a visual "SPD" warning at the top of the PFD OK. AOA audio set to begin at bottom of yellow, AOA vol 100%, inhibit AOA below 20 kts.
