I'm not quite sure about our RAF Brothers but the RN simulators are operated by current and serving aircrew. Some of the sims will have civil servants working for them but by and large when you walk into the sim for a sortie you will be taught by a current pilot / Observer who has to maintain his flying currency (slightly reduced - I think its 8 hours per month) as well as work the sim.
Therefore they will be on the same wonga as everyone else.
