I agree with the rosters. Hugely fatiguing, accident waiting to happen. IKA, nice day out that one...2 sectors, 1hr 45 each and back in time to laze by the pool!
I am not so sure I agree with the 'Days Off' quoted. As far as I am aware (and my roster has always agreed) Days Off down route count toward your 1 off in 8 duty days, but they don't count towards your avg of 8 in 3 months. You must avg 8 days off in home base. Don't get me wrong, you won't avg more than 8!!!
As for Leave, every 7 days of leave you take in a month counts as 2 Days Off. So if you take 14 days then expect to only get 3 days off for the rest of the month. In reality, they struggle to roster quite so close, but they'll give it a darned good try.
