I have never checked the flight times for accuracy Don. But I do know that it does not record all landings and takeoffs. P3D and FSX would record them all, so I think this is a backward step. Especially for simmers like me who set out to explore and test our skill by landing at any out of the way strips we come across. Sometimes it maybe four or five or even up to ten if they are close together. If it is a long strip, maybe just a touch and go. We can't even plan such a flight which will record our landings/takeoffs, they just show as waypoints.
So Don, I can quite believe your log is not recording correctly. And will check my flight times in future.
I think whoever designed the logbook feature only had tube liners or strict A to B simmers in mind, not bush explorers who test themselves by doing things that they would never have attempted in the real world..
