abr69,
The best thing to do is to ask the operators on type, face to face. Did you ask them while on the job?
If not, why don't you pay a visit to a RN and RAF sqn and talk to the individuals. it won't take up much of your time and in my experience the sqns are always willing to show you around and have a crewroom chat.
I also suggest you use the search facility to go through past threads. There's a wealth of information on here - use it.
Good luck.
