RAF FOA vs FOA (ATC)
Just to clarify a few points made in this thread; all AFCOs should know the difference between the two seperate, though connected trades. If you ever wish to be a controller then apply FOA (ATC) otherwise your only subsequent option to become a controller is commissioning, and that is not the easiest of routes. Generally speaking, if you join FOA (ATC) you will spend your time in an ATC tower and not Stn Ops or Flt Planning (although there may the odd exception out there somewhere).
Just a little insight for you (although it can change day to day...), no fresh applications for FAO are being accepted at AFCOs; however, FOA (ATC) is now a priority trade therefore the RAF have significant vacancies.
If I was going to Cranwell for the controller aptitude tests then I would go as smartly dressed as possible - though only an apptitude test it is still part of the selection proceedure.
Hope this helps - back to ATC in a few weeks time...damnn
