In 1995 the BBC ran a six-part television series called 'Flying Soldiers'. A book of the same title by Tim Lambert was published by BBC Books. It follows a course of ten going through Helo training with the Army.
It's obviously a bit dated now (in fact it's pre-DHFS etc.) However, I reckon it still gives a useful insight into the pressures of flying training and the AAC. I don't even know if it's still published, but I suggest if you can get your hands on a copy it would be a useful read.
Best of luck me olde'
