Cumulative Flight and Duty Limitations


Rolling 672 Limit: 100 hours of total flight time in any consecutive 672 rolling hours.
Rolling 365 Day Limit: 1000 flight hours in any 365 rolling day period.

Part 117 rules also contain two flight duty limits, which can be tracked in LogTen Pro with the FDP fields (specifically FDP Start, FDP End, and Total FDP):

  • 60 flight-duty period hours in any consecutive 168 hours
  • 190 flight-duty period hours in any consecutive 672 hours

In order to ensure accurate tracking of duty times, make sure that the Duty->FDP Total field is being updated. We recommend entering your FDP Start time on your first flight of the day and FDP End time on the last flight of the day.
