Note first picture.

I think it's easy to see how a pair of AOA sensing ports could be
added to a glider nose.

There are a number of AOA systems using that technique already on the
market, but no glider pilots have reported on them that I can remember.
It's time to stop talking about them and instead, install one and try it.

I am considering installing an AOA probe when I get my new motorglider
(Phoenix U15) next year, using one of these unheated probes:

They are cheap at $200, and there are no additional costs for the panel
indicator, as it displays on the Dynon SkyView panel display the glider
will have. At that cost, I'm willing to experiment without knowing that
it will be useful.

Has anyone used one of the Dynon AOA probes? How well did it work? Did
it seem suitable for gliders?
