The D2 integrates wirelessly with several 3rd party apps so a programming API exists. Whether Dynon would make the API available to glider App developers (like the XCSoar team) is unknown.

The Dynon allows you to tie into the main DC supply, but it also contains an internal battery with 4-6 hours of juice. I suspect that there is a fail over mechanism.

The Stratus2 AHRS https://www.foreflight.com/products/stratus/ requires an 'Ipad' but it also offers Synthetic Vision and ADS weather (not offered on the D2.

The Dynon is nice (I've flown one in a friends Mooney), but remember that the speed is GPS based; in a wave situation that could get interesting! If I flew wave and wanted a full time AI it would be high on my list. The Stratus is real close, if it was supported in my Oudie2 I would take a real hard look at it!

With all these new devices including the phone apps with glass cockpit, I wonder if the rules committee should just suspend anyone from SSA events for several years if they are cloud flying, instead of making contestants disable the AHRS in their butterfly or LX? Just a thought. I frankly think having a back up in case is a great idea, and I think it is exceptional stupid to intentionally illegally cloud fly in the USA without an IFR clearance. Any accident could seriously undermine all the other glider pilots. Years ago when I regularly flew out of Minden I heard many pilots talking about getting 24,000 feet or so in a thermal. I tried to speak with these pilots and explain the consequences of such mindlessness. All to no avail. I tried to get Larry Sanders to address this issue again to no avail.

Unfortunately (or fortunately!) clouds don't appear on igc files. It might be tough to discriminate between folks who fly though the wispies near cloud base (that is, most of us!) from those who take a few turns inside a cloud.

It's been discussed within the RC and with a number of CDs. I've personally looked a flight log files and weather data for "suspicious flights". We are talking about a relatively fine line in terms of being able to line up glider altitudes, locations and time off of a flight log versus some sort of estimate of of the cloud base - at the same time and precise location. The cloud data is neither granular enough in terms of height and location nor cut finely enough in terms of time (clouds form and dissipate) to make any definitive determination as to whether a glider was IMC or in violation of FARs for cloud clearance or whatever metric you want to use. The exception might be egregious departures deep into significant clouds that are well established. This is the main scenario for gaining material competitive advantage versus running in and out of the wisps at cloudbase. In any event, if you fly in cloud and you get caught expect furious vengeance and application of penalties from the CD.

I will let the sleeping dog of cockpit video cameras lie.

Keep your airspeed indicator and altimeter and replace your mechanical
variometer with the Dynon D2. Problem solved!

Dan, I haven't had a mechanical vario in my cockpit for 14 years!

And getting stuck in a lennie is not a big problem out here in the midwest! So I'll just continue to comply with the FARs and wait for something I can afford.
