Mercenary
Whilst the MCC is about the multi crew aspect you still have to fly the sim, you still fly routes, you still fly ILS' and non precision approaches (well, we did anyway), and you still deal with the emergencies, we did alot of hand flying on it which obviously meant we got used to how it feels and reacts. Had I done the MCC on an FNPTII I would have been in for a shock on the assessment.
The comments about the airlines not giving a stuff where you did the MCC are correct, but if you are wise you can get more out the course than just the MCC.
