So, looking at the new tables A and B. If you are unacclimatised (more than 3 hrs from HBT) then table B is applicable. However if you have not gone as far East-West as 6 time zones then no physiological rest (7.1.21.3 B and B). All references to a leg stretch pilot under table B refer to 7.1.21.3A and B, so as far as I can see whenever you fly home from a 4 or 5 hr timezone routing you are not going to get a 3rd pilot. So DXB to HKG regardless of time of day or length of sector (<10 hrs) will be a 2 man operation??
