I don't think NMEA 0183 supports stuff like altitude, pitch roll, yaw, etc. (Its a Marine standard, boat people)
I don't know if the 10A puts out NMEA 0183 or not, I haven't looked into it.
If you have any info, please share it, as this might be a worthwhile project....
One EZ guy that might be of help is Chuck Busch at TrioAvionics. He is their electronics/software wizzard who has had to figure out all the various data streams from a zillion different GPS units, some standard NMEA, some not, to interface with the EZ Pilot. The EZ Pilot has a built-in capability to recognize which/what data stream it's getting and self-configure, as I understand it. I believe that about the only 'modern' setup that the EZ Pilot won't work with is the Any Where Map system because they don't (didn't?) put out some critical piece(s) of data needed by the EZ Pilot (track error???). The AWM folks were supposed to upgrade their software to do this right almost a year ago, but as of a few months ago (~Dec.) when I last talked to Chuck about this it still hadn't happened. Chuck said they were more interested in developing real-time weather software than fixing the GPS data stream for the EZ Pilot.
So, that's about the limit of what I know on this topic, and it's all second hand.
