Often wish I had copied the previous techlog pages from the 777 I operated about four years ago. The aircraft had done ten sectors around Africa and the Middle East carrying our wonderful prime minister. With a variety of management captains the MINIMUM arrival fuel was 30 tons! The interesting one was a ten minute sector with 32 tons remaining. The aircraft arrived at LHR with 36 tons.
We almost didn't have to refuel for our sector!
One rule for them, one for us!
