5150 the reason the discussion is being sidetracked is because.....who is this total time for the benefit of??
If CAA for licence issue (CPL/ATPL) then they accept hours in sim as part of your training.
If you are calculating hours for an employer, then they are only really interested in actual flight time hours. Many airline application forms will ask for Flight Time and aircraft types that these were acquied on.
If you have Advanced Sim hours, (737 Level D etc) you will probably also have a type rating, however again actual flight hours on type and how these were acquired is of more use to an employer.
If you are a FrATPL with some hours in a jet sim but no rating, its irrelevent as any new type rating course will involve a complete syllabus not bypassing some bits you have done in a sim before.
Best way is to ask them...then post it here!
