I dont really undersatand your question but class Bravo airspace can be refered to as an upsidedown wedding cake. As you get closer the airspace becomes lower until it eventualy goes to the surface.
hope this helps

In FS the entire world is modelled to use the US ATC system. This is not entirely realistic of course but does make it easier on the casual user who now does not have to learn 200 different systems before moving to VATSIM
It's also a lot cheaper to develop this way which means you pay less for FS than you would have otherwise.
