I know of a ryanair driver who had done 1200 hrs for the year.
He was taken off line but the following day was told that because they were short of crews he would have to pitch up and work.
The 900 hr a year rule was devised when the airlines were flying long haul. I do 700 hrs a year short haul a year, doing 900 a year or more would be just unsafe.
I wouldn't like to fly on a ryan with a pilot on his 5th or 6th sector of the day when the weather is bad and it has all been going wrong.
