Perhaps someone with an account can look to see if raw airspeed is available since that is not part of the free offering
That’s quite possible, of course. It just caught my eye, however, that the airspeed went up and down significantly all the time during this one last flight, while it was always constant during the prevoius ones... that appears a little strange to me.
