Within a UK CAA CAP371 regulated crew duty day 411?
Yes, with a crew change at the refueling stop.
Augmented (preferred) or double crew sent to the Afghan end to cater for possible loading/cargo/fuel delays, which by the way, are the charter customer responsibilities.
Sick of this crap being used to belittle the RAF AT system.
Nevertheless, the RAF 'performance' is what it is, and if it was better, this thread would not likely be here.
