You can, BUT(!) if you have a joystick, or a homebuilt cockpit: you'll never make it. (Except if you've a lot of money.) The FSX could do it, but the yoke, the cockpit, the envivronment has to be like the real thing (i.e. hydraulic systems for the yoke to feel like the real one), otherwise it doesn't matter. And don't forget that the procedure is also important, if you practice it in FSX, you'll be more confident of where is what and you won't start to think in a dual-engine failure about where is the APU start switch, and how to start it. :LMAO:
