Today, I used FIF to record a short glider towing flight, as a test for the trace recording.
After the flight, when I zoomed on the map to see the details, I was surprised to see that the trace did no scale with the map.
In the attached view, I have zoomed on the runway and it looks like my flight completely happened on a small portion of the runway.
Luckily, this bug is not observed when the trace is displayed from the flight log, but only on the trace displayed on the moving map (in flight).
