For you guys who fly the regional flight ive seen some flights are over six hours long with a stop so would these flights carry S/O or would you fly both sectors return next dayor same day.
Normally only two pilots are carried unless one of the sectors is longer than 9 hours [8 hours if the sector goes into the late night period (0200-0600 local time where the sector commenced)], in which case a third pilot must be carried.
For example, over the summer period the 777 does HKG-BAH-DXB with two pilots - 1st sector 8 hours 35 minutes, second sector 1 hour 15 minutes, total flight duty period 12 hours 10 minutes.
