Weakness' post is pretty accurate, but add on a bit to all the numbers, full time fo now 58k after the inflation pay rise, so ppy50 about 48k.
I would also say you could realistically expect a bit more than 1000 a month in duty rig (flight pay) and fda in the summer.maybe 1300 or so. Not all of the fda is taxable, I think about 20% is tax free. But yes it's not pensionable.
Working day off payment is about 470.
