Default looks like a decent AoA for me!!!!

....anyone have the inside scoop on the company, availability, cost?
dealers?
one sidebar says ...." from $595 to $895"

.......... surely for a 'certified' instrument, they are missing a couple of zeros?

The "About Us" on the web page is interesting...

.....As Co-Founder of Aspen Avionics, Mr. Bethel has continuously worked to bring innovative technology and solutions to the general aviation market, lowering costs and simplifying installation....

I guess there is some serious past expertise here...

It is not TSO’d (“certified”). Their web page says they hope to gain approval for part 91 use, similar to the approvals Dynon and Garmin have obtained.

AOA feature without a probe? That's simply not possible for a direct measurement of AOA - maybe he's using a computed AOA based on airspeed and G-load?

And if we're venturing into computed AOA, that gives me an idea. How difficult would it be to add a layer of computation to account for significant roll-rates and filter the AOA for the unfavorable wing, to alter the alert points for that case? You'd obviously need some flight test data for each model that it was installed on, but that would be quite interesting to implement. Edging into "envelope protection" at that point, or at least "envelope alerting".

I had a sneak peek of what these guys were doing a few months back. Bill Shuert showed up at the NM Backcountry STOL course with a prototype AV-20-S unit in an aircraft. I knew Bill from his Sandia days and did some test flying for him back then. The new unit was pretty impressive. Jeff is to what modern digital avionics and systems as what Steve Wozniak was to personal PCs. These are some really smart guys and I am glad to see they have started to get the word out.

And Greg. I think Aspen does a probeless AOA also. And Jeff holds the patent on the Aspen EFD-1000. So it makes sense his new device does the same.

Default probeless?

...total neophyte here, but looks like there are clearly just two ports on the back of the case....so is that just pitot and static for airspeed?
you'd need a third for the 'dynamic' air pressure?

the Dynon I have toyed with seems to have three ports....so that would be pressure derived AoA, right?
