Another clue might be the fleets they offered this on. They're offering this to line pilots on every fleet except the Airbus. Why would that be? The Airbus is the only fleet that isn't allowed to have the PI do seat support while running the panel. Can't do it in the 320 sims. You can in the fleets they offered this May deal on.

I think they wan't to use line pilots to practice and get proficient on having one PI do seat support while running the sim.
