Sadiq,

if you are looking for general information on crew rest recommendations etc, check for the UK CAA papers - CAP 372 is about the definitive publication.

Dr. Mark Rosekind of NASA (now runs his own consultancy) also did a whole heap of research on this topic.

Emirates has a bad reputation, going by bar talk - I know some people who fly there - on crew rest. But I doubt you will find anything published specifically on this issue with EK. Unless you can get hold of their Operations Manual, but I can't help you there.

As B-747 said you should look for another topic!
