Test of knowledge.
Do what real pilots do. Sit in the aircraft with the checklist and name all the switches. Repeat until you know what each one does, and when to use it. My guess is that even some of the best DCS pilots do not know emergency procedures for the aircraft they fly. It is mostly "I'm hit, EJECT". There are proper procedures for engine out, loss of hydraulic power, loss of generator power, etc. You would be surprised at how realistic some of the aircraft are. But, of course system failures are not yet accurately modeled.
