The slide for linguist isn't accurate either. Post Generic course, the guys and girls go to Beaconsfield/Chicksands for academic language trg for up to 18 months, then around 8 months with 54(R) Sqn for applied language trg prior to brevet award. The actual OCU (flying) phase with 54(R) is only a month or so though...assuming that there's an aircraft available of course!
