Just bear in mind that several operators have command course selection procedures that have scenarios/dilemmas that will have no clear cut answer.
If you can't argue your case for a decision in the sim against an experienced training captain, that may have been outside the limits placed in the POH or AOM, depending on what it's called, then are you sure this is the career for you?
As other people have already stated, the guys on the ground have big expensive lawyers, and all the time in the world to review a decision you might have made in a very small period of time.
In most cases the POH is the best source of info and ideas you can have, but it aint perfect.
At the end of it all, you're the most visible target the lawyers will go for.
