Swapped SkyView for HDX, now AOA way off

[Jeff1]

Swapped SkyView Classic for HDX. Used to have aural and a good green, yellow red indication on panel. Since the swap no aural. Did a stall series to recalibrate, now solid red on screen, no yellow or red. Suggestions…?

I have the same issue. But mine was a complete new install. Has been 2 years and have not resolved the no AOA audio tones. The visual bars works. I have done a series of troubleshooting with tech support and still no good results..

Mmm. Interesting. Have you guys dug into the settings in you HDX menu.? Specifically the alert settings values for AOA.
If you do a search i believe on this site. You can find settings that seem to have worked for aoa

. Thought that if I did more it would be better, not so. I did two series of stalls, clean half, full And ended up with solid red on screen. Went back and just followed the on screen instructions, one clean stall, recover and push stall button. Now I have the red, yellow and green back on screen. But no aural.

Received this from Dynon

Don Jones (Dynon Avionics) Jan 15, 2025, 9:55 AM PST Jeff, Lower the starting percentage way down to see if audio works. I suspect the AOA percentage is never getting high enough to start the audio tones. You can export the user logs and email them to me and I can verify that.

Jeff smith Jan 14, 2025, 5:48 PM PST I think I have the visual AOA back on the PFD on res, yellow and green. However, still no audio that was there with Skyview Classic. I have gone to settings and have it set to start at 85% and solid at 95%. I'm assuming that is 85 and 95% of stall. Previously I had done a stall series of clean, partial and full flaps. This time I just followed the on screen instructions and did one clean stall, recover and then push the stall button.

I have not lower the percentage of my values but still no audio. I tried the same values as Jeff and also tried everything at the highest levels
No joy

With respect - 'the man' (Don) said "Lower the starting percentage way down to see if audio works" - at least do that first.

With even more respect, I haven’t gotten to fly my airplane since that post was up. Los Angeles are full of TFRs and it’s just not a good time. My intentions to say was I have done all of the above except lowering. If you not going to be helpful it’s better not to say anything.

My apologies, IMO it wasn’t clear enough about your situation- it appeared to me that you moved on to another solution rather than do the simple task.

No worries…. No no I will definitely try that recommendation. At this point I will try anything. I have done a lot of troubleshooting with Dynon but was never told to lower numbers.

Have 2 classic D-1000 screens with the heated Dynon pitot/AOA. There does not appear to be a way to change the range of the AOA. The green bars disappear as speed reduces, but the audio chirping does not start until the yellow lines are reached, and it is very narrow range to the solid sound and stall is reached. This is in RV-10

I recently did the swop over to twin HDX and experienced the no audio issue with the AOA. Contacted Dynon and was advised to just try increase the AOA VOLUME setting. On the D-1000 I had it set to 45. I found that on the HDX there was no sound at all until I increased it above 50 and the setting that gave me the same audio level as before was 65. Might be worth trying.

Look in the AUDIO SETTINGS menu you can change the starting point of the tone. Read the tiny wording at the bottom of the screen it tells you how the settings work.

 

[Jeff1]

After my HDX swap, I had 85 and 95 with no audio. Dynon had me turn it down to mins, 50 and 65. High low .... nothing

 

[RB-RV9A]

Seems like few people are having this same issue

 

[jakej]

What seems strange to me that several people are talking about the volume only setting, why ? My volume is set at ~85% & I usually change the AOA percentage of actual 'stall' (AOA break) to something like 65 % - no issues with audio & I've done a lot of installs however YMMV with the audio.
btw - HDX Pilots manual RevP page 12-20 tells you the 'basics', it may be helpful to some.

 

[Stevec]

I guess I talked about it because that was the issue. The Starting percentages etc remained the same as before and they do not control the volume only where the audio signal starts and stops relative to the yellow and red sectors on the AOA gauge.
it appears the HDX audio signal output is weaker than the Classic one which is why the volume needed to be increased in my case. Originally on the classic I found the volume level of 40 to suit my needs. I wanted to hear the AOA sound but didn’t want it to be distracting. Now it needs to be 65 for the same level

I followed Dons guidance and turned down my numbers to minimum of 50 and 65. This isn’t a volume level (I think) but percentage of full stall. I had aural To start at 85% and full on steady at 95%. I turned my numbers down to minimums of 50 and 65 and today it WORKED. Again, Although the lower numbers don’t make sense as a percentage of stall, it worked as desired and I got the intermittent chirp in the flare.

Hi Jeff, I am having the same issue. Unfortunately i am on a business trip out of the country till mid March. I dont want to forget about this. with no hurry could you share a screenshot of your setting so i can try the same setup when i get back!
Thank you so much.

 

[jakej]

Didn't I say that in post #15 ? maybe it's something to do with the coriolis force.

 

[Jeff1]

Sure, it will be a few days.
All that matters is the result, however the verbiage in at what percentage of stall do you want the aural warning to start chirping and on solid doesn't jive. I had mine at 85 and 95, with nothing. Dropping it back to 65 and 50 worked, although in the flare I'm a lot closer to 85 % of stall rather than 65%.
