[X-Men, Marvel Comics] How dire does a situation have to get for Charles Xavier to go out on the field with the X-Men.

I don't know if it necessarily needs to be a dire situation, just one that requires his specific skills. It doesn't have to be a fight, sometimes it can be some kind of diplomacy or communication. Sometimes the X-Men need to appear as a united front, and for that it can help to have the guy who runs the whole thing.

Otherwise, if he really needed to, he's probably powerful enough to assist the X-Men in skirmishes from the school, using Cerebro if he needs it.
