GPS/AHRS data

[willbt]

Has anyone had any experience recording GPS position/altitude and AHRS/Gyro attitude data for download? This is of interest for aerobatic instruction and debriefing. Ideas? I know there are a few setups out there (pcaviaonics.com) that input GPS and AHRS type data into iPaqs and such, so hopefully there are folks on VAF that have some experience.

Yes, we have had very good luck doing this with the GRT EFIS - it was built with real-time recording capability. I am pretty sure that other popular systems do it as well. In the GRT, you simply record data to a thumb drive, and then (with a little decoding software) you can look at it on your PC.
