Slightly off topic but still somewhat related...
I understand that a professor in Swinburn Uni in Australia Dr.Peter Bruce is working on an airline operations control simulator. I think that's an interesting idea that could be very useful for airlines especially when training new hires.
You don't really need a simulator to simulate flight dispatch as any real flight planning system can be treated as one as long as you don't file anything live in the ATC system. You don't need real weather updates as any decent instructor can create a scenario far worse than most you will encounter in real life
An ops control sim - now that's something I'd like to see.
