Answer
We have: 1. Time out: out of the gate doors closed and push back 2. Time off: wheels off 3. Time on: wheels on the ground 4. Time in: in gate doors open, first passengers left the airplane Duty time: up to 14 hours, means from report time which starts 45 min before a schedule flight in my hub, and 30 min in an airport other then my hub, and duty ends 15 minutes after arriving, means time in. duty time can be exceeded to 16 hours if needed. If I fly up to 8 hours I need 9 hours of rest 8 hours to 9 hours required 10 hours of rest 9 hours or more required 11 hours of rest Now we also have reduced and compensatory rest: 8 hours I need 9 hours of rest- can be reduced to 8 hours of rest but then I will need 10 hours that must begin no later than 24 hours after the beginning of the reduce rest. 8 hours to 9 hours required 10 hours of rest can be reduced to 8 but required 11 hours of compensatory rest 9 hours or more required 11 hours of rest can be reduced to 9 hours but required 12 hours of compensatory rest Now we are not over yet: FLIGHT TIME LIMITATIONS PART 121.471: (AIRLINES) Daily 8 hours between required rests Weekly 30 hours Monthly 100 hours Yearly 1000 hours So as you can see it’s not only flying the plane its more then that, and you have to be very careful, the FAA is always looking for pilots that ignore this rules, so I have to make sure that I am always legal.
