I agree with plastic. I done the oxford course on the 737-400 learnt the same as the guys in the turbo prop sims BUT I got 20 hours operating a 737 with all the bits plus two crew. I now feel WHEN I do a sim ride I will have little problem coping. The only word of caution is the low houred guys with me did have a problem with the actual flying and could not wait to hit HDG SEL/L NAV given the option, so they might not have got the most out of it.
