Interesting point that.. In two and a half years instructing in the sim I never saw anyone select the starter on by mistake except during an in-flight restart after flame-out.. on a few occasions someone would forget to take the start-switch out of 'start' and then discover that they couldn't bring on the genny.. the rest was fun to watch as the second genny hopelessly overloaded would burn itself out after five minutes or so.. Making this mistake with both starters before flying would create havoc and it would be impossible to even get airborne.
