I'm a CRM instructor for the Navy... our program is probably different than the 121 programs, but the principles are the same. Ours is based off of the airlines programs. We use the seven criticle skills. If you want to learn some buzz words to throw out... go to this webpage... check out each of the seven and try to grasp their concepts and how they actually all work together.. For example.. you can't display leadership in the cockpit without good communication.. CRM starts the night before your flight by getting enough rest, and continues until a good postflight debrief is conducted. It's not just feeling good about things during the flight.. To get a scenario, and properly identify the components that lead to a breakdown doesn't take long once you learn the basics. (For example.. The captains' over confidence made him complacent (I've made this approach a 100 times, we're fine), which was made worse by the FO failure to be agressive when he recognized the problem (the Navaid and FMS don't agree)...) Good luck..
