To help the scorer, it would be nice to present a USB stick with only that day's contest file. But how can one delete all the other flight logs that end up on the USB stick, too?


From the updated Powerflarm manual:

CORE has internal memory for around 100 hours of flight recording at a 4s interval. Flight recording automatically starts when the aircraft starts moving and ends when the CORE is switched OFF or after more than 10 minutes of standstill. When the memory is full, the oldest flights are overwritten first.


Regarding the USB stick, the guys above are correct. The scorer shouldn't have issues if you have a valid .igc file for your contest day on the stick. They will find the correct file. Personally, I use a clean stick at the start of a contest and don't bother erasing anything until after the contest.
