However when I display the schedule and wait for a time event to take place for a plane that is listed it is not doing anything ... arrival or departure.

I am currenlty at KPHL and I see many aircraft in the sky but hardly any moving around on the airport grounds, maybe one or two.

Also will there be GA introduced into TG? I have never seen any GA flying around or move at an airport.

Not much help here, is there?!
