Down to one pilot - what's the procedure?
If (choice-of-deity forbid) you lose the other member of the flight crew, what's the procedure? I assume that if (by some chance) there's someone from the same airline and same type rating then they'll get drafted in to the now vacant seat.
(And if you're the co-pilot, and he's qualified as a captain, does he assume command?)
But after that, what's the order of choice? Would you draft a PPL in preference over a member of cabin crew, or would you just leave the seat empty?
