Class D is an airport with a control tower. It is the most basic towered airspace, usually with no radar (I think). Just a tower. Class C is a bit more complex, for bigger airports with bigger and faster traffic. It has tower, but then also an approach radar control to sequence planes, etc. Class B is almost the same as class C, but much bigger and a bit more complex. That is a very basic run-down of the surface-based towered airspaces. There is also class E airspace which is everywhere in the US at or above 1200' AGL, with it sometimes down to 700' AGL. This is controlled airspace (ie. you should be able to contact ATC for services if needed). Class G is completely uncontrolled and goes from the surface up to the floor of the class E. Class E goes up to 17999' MSL, where at 18000' and above is all class A. All the different types of airspace have various entry require,ents and weather minimums for VFR traffic.

For Class C, I'll have to say BNA. That's like a hub for WN, and the last time I flew in there(as PIC, not pax on an airline) they were using all 3 parallel runways at the same time. It was crazy busy, but only a Class C airport.

I have total numer of movements for the centers, towers, and approaches for 2004 if someone could post them. I tried to post but all the facilities and numbers ran together. I tried to get them to align but they wouldn't.
