OK, to anyone who may be curious about how to make planes MOVE at the airports, it appears to be working (remember, I have downloaded the beta). Live or not doesn’t matter to me, I just want to see moving planes. This is a screen shot of SJC:
As CasualClick noted, I changed to REAL-TIME ONLINE. My Ground Aircraft Density is at 75 and both of the Generic Plane Models settings are OFF. I don’t know if the other settings matter.
I have AIG installed, but I’m not using it because I’d rather not have the overhead if I can get away with it.
Just a few caveats - you may have wait quite some time (10 minutes or so) for the traffic to start moving. And sometimes the planes act irregularly, but hey, it’s beta. I’m marking this as the solution since it’s working for me.
