Sambo P...
I am aware of
Flight Aptitude Test Workbook RAF Cranwell FATS, (fatpass.co.uk) I was helping a family friend through his prep for the FATs recently (FAA) and we stumbled upon this gem. It is a very good resource for the speed distance time aspect of the FATs. If you wish to fly for the military, then this is a valuable investment. For the price of a couple of pints, I'd go for it.
Good luck with OASC Sambo
