RN History
Don't worry too much about the history of the Fleet Air Arm. A broad knowledge of major events will suffice. ('Task Force' by john parker is a good read...).
The AIB is looking for pilots of the future, so a knowledge of where the FAA is going to be in the next few years will impress. Obviously you can't predict where you will be flying (if you know that...can you inform the rest of us) but what the FAA flies now i.e sea king 4, merlin, lynx, FA2/GR7 and what is planned to replace it..... JSF/BLUH?/SCMR...well, who knows!!
Finally, knowing where we are deployed now (Aircraft and Ships) is very useful information, along with the reasons why we are there. (Iraq/Falklands/Kosovo/caribean(sp?)/etc)
