Thanks Gentleman, appreciate your input. As I understand it it means that although it is labbeled Inflight Relief, you are as a commander not allowed to leave your seat during all phases of flight, if there is no qualified licensed person available to take the your seat. This means in the 3 man cockpit concept in SQ that the captain in real time is limmited to 2 man crew hours. Do I see this correct or do I miss something??? Does the 2 man actual stick time limit come in play here?? Believe it or not there is no guidance on this subject from the authorities (Surprised??)
