Flight logging stops when your speed drops below 10 knots and stays there for at least 20 seconds, as I recall. This is quite easy to test in a car.

Hi, yesterday after 1-hour flight landing flight log continued to count for another 20 minutes when airplane was at the parking. As a result in the log I had wrong landing time (+ 20 min), wrong flight time and wrong average speed.

I understand log starts and stops automatically depending on speed.

Is there a way to force it to stop manually or at least to see if it stopped or not?
