Aerovonics AV20S

Are there any new PIREPS on this?   Mine seems quirky with AOA compared to my Bendix King AOA.  I had read a previous comment that AOA in a turn was not correct but a software fix was being worked on.  My true airspeed reads high compared to the calculated on my Garmin.

Is it located on the right side angled panel of a J or later?  If so, the angle makes it do strange things.

He has an F

I don't think there has been any update to the no sensor AOAi... posted around here...

Best regards,

Whoops!  Didn’t think to look at model.

I don’t have the original F panel. I did measure the angle of the panel and corrected the suggested AOA set up numbers after talking to Bill Shuert of Aerovonics.  Have tried several setting around his suggestion but can not get what I think are realistic readings.   High Angles seldom remain constant for what is a constant AOA on my BK AOA.   Just looking for someone who feels like they have theirs working. Also looking for someone who sees agreement on their true air speed reading compared to other instruments or calculations.

@Gary0747, there are a number of reports here and elsewhere of problems with the AoA function of the AV-20S. I've heard about a potential firmware/software upgrade that may address the issue, but nothing confirmed that I know of.

That said, I still decided to include one along with my current ADS-B and GPS install, mainly as backup for the primary vacuum AI.  I should have my plane back from the avionics shop in the next couple of weeks.  Will be sharing my results.

If the AoA works reliably, then I consider it bonus gravy on top of the AI, since so far, I haven't heard anyone reporting that the AoA is working as hoped/expected on these units.
