This roster is a good example of how things can be difficult for the system to work out. The two decent breaks are not a case of it being kind to me, but are forced by hitting two of the flying limits. The first break ensures that I don't exceed either 100 hours in 30 days, AND also the 30 within 7 for the two man sectors between Dubai and London.
The next longer break is forced by the fact that I'm approaching the annual maximum hours, so the system is looking back to ensure it remains below 900 hours in 365 days. Consequently, it ends up crunching some trips together towards the end of the roster, and again pushing up towards 100/30. At the start of the following roster, there will be about a week before I go on leave, in which it will be almost impossible to give any flying, and in the week following the leave, a simulator, and probably an LA will have to be planned (and we're now talking about the end of June). Most likely when the next roster run is done, I'll tick the option that allows leave to be slid to give a better flying outcome.
One more issue is that after working within all of these limitations, the total amount of work that it has generated is 7 hours below the target. It is allowed a margin, but it has exceeded that, with the result that I start the roster 'owing' the company 5 hours of work (for which I'll be paid, as it's not my fault it couldn't generate it). That means I'll either have to be available on what would otherwise be some days off, drop the 5 hours unpaid, or, most likely, do a standby....with the attendant risk that has of laying waste to the entire roster.
Two days (most likely in the middle of the long break) will also be grabbed by the sim schedulers.
I'm just one person. Multiply this by a couple of thousand, and you can see how difficult the entire scheduling exercise can be.
