Not to sound like a total nerd, but I have heard the instructors call it the Kobayashi Maru. They give you a couple failures which lead you to make a decision between two outcomes, and both are bad. For instance, you will lose deicing and pressurization at 18,000' and your choices are to stay at 18,000' with low oxygen in the back for the passengers or to descend into heavy icing conditions below with no deicing working.

They know it is a bad situation, and they just want to see your decision making skills. In several of the scenarios, there are no good answers. It is a session that is designed to test your leadership and decision making, as well as systems knowledge, not your flying skills.
