To explain our logic:

There is a minimum airspeed setting for AoA to trigger. You must be going faster than this and have AoA above your threshold to hear the AoA alarm.

What we will not do is CANCEL an AoA alarm that is going off at the time that airspeed goes below the threshold. However, if the AoA drops while you are slow, then the AoA alarm will stop and should not come back unless you speed up.

If you're getting AoA alarms that are going from off to on while below our speed threshold, then we have a bug. If they are persisting as you slow down, then that's by design, but of course we are willing to reconsider. The AoA has been like this on these products for 3 years, but we've sure never been aware that it was causing issues like this.

Ian,

I am pretty sure the logic works fine on the minimum speed to arm the AOA alarm, at least on 5.4 and in my plane it does.

The issue with the alarm continuing to sound all the way to little to no speed is not new, it goes back some time, quite a few questions about it in the archives of the Dynon forum.

I just accepted that this was the way it had to be in order to warn someone that is in a very deep stall.

Maybe you could allow the AOA Alarm to be acknowledged or silenced with a button push?

That would be an excellent feature and would solve all the "issues".

Default +1 on the button push

same issue with my -7, the button push would be consistent with the process to remove other "latched" alarms on the Dynon.

We don't have the AOA in the RV-8 but I did wire up the Dynon's audio alerts thru a potentiometer (volume control) hidden away under the bottom left side of the panel, making it easy to reach under there and give it a quick twist to silence the alerts

Most of the time I just ignore it once the wheels are down but it can make it hard to hear the tower controller's instructions on when to turn off and contact ground so I keep mine turned down lower than I would like. I can't reach my volume pot while strapped in.

Mine has this problem also. While annoying I'm used to it, but my new passengers don't think so highly of it. A button press to silence would be great.

This problem could be fixed if you guys would all just put nosewheels on your airplane

Default Works perfect

in my 7.
I calibrated the D10A AOA 3 years ago and have not experienced any nuisance alarms. I do plenty of stalls and get a solid tone just prior to the stall buffet.

Bill,

You never experience a continuous tone after landing till you slow way down?
