To make a correct assessment and therefore decision you need to get yourself on an acquaint course down at Culdrose! Get youself in a pinger or bagger and really understand the difference between front and back.
My money would be with the baggers or 849 as they offer best of both worlds, use to anyway. Not because they do a more exciting or important job but because 849 used to only fly with 3 crew, 1 P and 2 O's as they were so hideously over weight before fuel. That meant the O's had to be proficient at many of the startup/shut down procedures and even flying left hand seat. Had to do a fair amount of sim time too!
Therefore if you get yourself on an 849 flight you will likely get lhs time, listenning to a few radios, fuel checks every 20 and flying around picking your nose for 4 hours wondering which bar to go to or how to spend your weekend whilst being distracted by the O's providing early warning, real fighter control to the point where you get your cap 1/2 mile behind in a 30 degree fox 3 cone in all conditions, if you have any cap to play with that is, surface search, OTHT over horizon targetting, ECM and more. Either that or look at what 854 have just finished doing in Afghanistania!
Pilot flies a barrier on station and used to have the exciting task of getting from 10k to 10, feet that is and in shortest time possible in order to keep a bandit on the screen moving at 14 miles a minute or more. Not to be confused with looking for IEDs which dont tend to move that quickly.
With search water 2 maybe thats not needed but down the back you are an airborne tactical airwarfare controller and often the only voice on the net in harms way. As others have said, if you are looking for naval career outside of flying then O gives you more options. But I served with P's who have recently gone on to command 23's so.. both types are equally as important and after all the bull and banter as respected given the trouble it takes to get where they are. Pilots usually spout off a bit more and use their hands when talking but as others have also said THE MOST important thing to remember is that you are Naval officer first and foremost, a Jack of all trades and master of your own!
You'll be trained to drive any type of boat (note aircrew call all naval vessels boats, whether they are a sub or not, to annoy fish heads) from dingy, to whaler to frigate. Command a shore party, a plattoon of marines. Escape and evasion, survival techniques, firefighting, first aid, peace keeping, nav at sea, watch keeping, small arms, to drill as well as the RAF, drink more than them and beat them at cricket, my intake anyway .-)
Get youself on a POAC asap and if your liason officer doesnt offer one use your initiative! You passed AIB therefore someone has deemed you have one. Well done!
