If you've filed a flight plan the FAA will come looking for who's name is in box 14.
Regardless of who has "higher" ratings, etc....
It's not what we all said in the least. Who's name is in the PIC box in the flight plan has little to do with who ends up getting violated.
Again, the specific circumstances of the event are what needs to be considered. Generalities such as who's name is on the flight plan is far too general to be considered of value in attempting to determine who gets tagged for what.
