Background--I have a GRT Sport SX and EIS6000. Typically, I'll pull the USB stick from the EFIS after 2-3 flights and download it to a laptop harddrive--either for submission to Savvy for analysis, or just to retain in case a problem of some sort were to arise and I want to look retroactively for when it might have begun.
The GRT stores two types of files. One is an Excel CSV file, named GRT Flight Data Log. I've not used that. It always seems to be about 30 MB in size, so I assume those 30 MB are the "last data", and anything earlier is overwritten--but I don't know that with certainty.
The other filetype is a text document. Those filenames start with DEMO, then the date, then a five digit number. Those files aren't much larger than 15 MB, which is limited by the amount of memory in the unit. When that filesize is reached, it writes to the memory stick, and starts a new file with the same name, and a +1, +2, +n... extension. For Savvy analyses, the DEMO files are zipped together and submitted.
I recently pulled the memory stick to download the latest files. The CSV file was there for the most recent flight, but there were no recent DEMO files. I removed and reinserted the USB stick, even though given that the CSV file was present, a poor connection there seemed unlikely. Also, the 1 GB memory stick is slightly less than half full, so it's not a capacity issue.
I contacted GRT, who have always been very helpful. They (Jeff) suggested it was a settings issue. Seemed unlikely, as I hadn't changed anything--although I had updated the NAV database. Nevertheless, I checked the settings menu, took a screenshot of that (attached), and sent it to GRT. It's set to automatically start recording as I exceed 40 KIAS, then stop when I've decelerated through 35 KIAS. Jeff replied that my settings looked OK, and that basically he had no additional ideas why the DEMO files weren't being written.
Has anyone experienced a similar issue, or have ideas on a cause and corrective action? I spoke with a hangar neighbor this AM who suggested re-loading the system software (after confirming that I have good records of settings of course). Before doing that, I thought I'd check with others who have GRT avionics to get their thoughts/suggestions.
Thanks in advance.
