start flight data logging only when e.g. vtas > 60kmh (test via simulated pitot pressure)
stop flight logging when vGround & vTas < 40kmh for at least 1 minutes to also capture the landing and to be robust for high wind wave or acrobatic flight conditions.
After landing: close the flight data recording file, write latest sensor calibration values to the eeprom and dump to sd card.
Shall there be a feature to enable continuous logging via a sd-card configuration file?
