Does anyone here use the the automatic Foreflight logs as the time you put in your logbook? I've always just used the Hobbs but the Hobbs for my flight today was 3.2. Foreflight showed 1.7 on the way up and 1.8 on the way back. That seems like a pretty big difference to me. I'm thinking I may need to use a stopwatch next flight to get my true time from when the airplane moves under its own power to when it stops engine is shut down. Anyone else notice a discrepancy between these numbers? What do you use in your logbook?
