This is what the UAE CAR OPS says, freely available on the GCAA website:
CAR-OPS 1.1125 Absolute Limits on Flying Hours (a) No person shall act as an operating crew member of the flight crew of an aircraft if at the beginning of the flight the aggregate of all his previous flight times;
(1) during the period of 28 (twenty eight) consecutive days expiring at the end of the day on which the flight begins exceeds 100 (one hundred) block hours: or during the period of 12 (twelve months) expiring at the end of the previous month exceeds 900 (nine hundred) block hours:
Two pages before you can find the definition of operating crew member:
a crew member carrying out his/her duties in an aircraft during a flight .
There is no reference whatsoever to bunk time not counting towards those hours. However, our bosses claim that because the OMA is signed off by the GCAA, everything that is in there is "legal". I'm not a lawyer, but something doesn't smell right. EK knows it, the GCAA knows it but as they both have the same boss, nothing will change. Only pressure from other legislators might do, but don't hold your breath....
