Holy UAT, Batman

What would be cool would be if someone could have the traffic info stream out in NMEA instead of requiring Foreflight especially if it could output or the Raspberry Pi serial port so you could use a K6Mux to MUX the ADS-B UAT and TIS-B traffic into a normal glider display. Being able to overlay the FIS-B weather would be cool too. Yes I know that would require ADS-B out, but we may be required to do that in 2020 anyway.

How hard would that be?

You don't need ADS-B out to get FIS-B weather. Just line of sight to a UAT tower.

The Stratux software running on a Pi2 emulates a Stratus receiver that provides the same functionality. The data is shipped out in garmin GDL90 format via a wifi connection which lots of different aviation software and hardware platforms can display. Including free software that could run on your smart phone.

They are adding GPS and AHRS functionality to the software if you want to add those sensors like Stratus has, too. Its all open source so feel free to change what you want.

What in-panel glider hardware will accept GDL90 format information?
Or is there some sort of G'zinta box to convert?

Somebody needs to write a Pi2 software routine to output NMEA plus whatever weather format LX Nav is accepting. It seems to me the traffic data needs to go out on a serial port and the weather would be via WiFi hotspot since that is what LXNav is using. I doubt they are in a hurry to build something that would only work in the US so you'd need to spoof what they are delivering via cellular data and WiFi hotspot - assuming it's not encrypted.

You'd need ADS-B Out with the right configuration to get TIS-B except for the random output meant for other aircraft.

If there is one ADS-B out glider in a contest it will allow a bunch of other gliders to receive the data, although not with 15 nm radius. A few gliders could almost guarantee full picture for everyone for $120 an istallation.

RC can not make ADS-B out illegal. I already have ADS-B out as well as ADS-B in on both UAT and 1090 frequencies.

The prices of ADS-B out will be continuously coming down and installing one for experimental gliders is not a problem even today. With the Garmin new unit for $845 I am sure we will see more ADS-B out gliders soon if one already has a Trig 22 transponder, there is little reason not to do it.

There are more and more planes installing ADS-B out so even if someone does not have "out" they can still see a lot of traffic. That is true on Northern New England.

I would not have a problem with voluntarily restricting what I have in my cockpit for contest purposes as long as my safety is not jeopardized like with the Stealth mode.
