Do a Google search for online scanner sites for airports and listen on a regular basis, you'll soon pick up the syntax and the rythym. There are also sites that will list call signs and the references to the airlines they represent.

One thing to listen for is how pilots repeat back the controllers' instructions and civility of the conversations.

At Airnavsystems.com you can also get trial programs that allow you to follow flights and track their communications with both ATC and their airline communications centers.

Good luck on your writing efforts!
