All of the duty time aside.....and the same thing happens at US carriers flying 8+ hours with three crew members to Europe or somewhere. Captain goes sick...flight's done.
And to all the other carriers doing something similar....that was the premise of my original question as to where the PIC is physically located during his rest. I doubt if Qantas, KAL, Singapore et al has the PIC located some 75 mtrs with 300+ pax inbetween his designated rest area and the cockpit. If it doesn't matter, why did Boeing build the aircraft for FAA certification with the rest facility directly behind the cockpit. It would be interesting to see if any other regulating authority besides the GCAA would allow this; the PIC in the aft of the aircraft with no other PIC "qualified" on board.
