Aircraft scanning can be a totally different world. In fact, most of these specialized areas of scanning (railroad, aircraft, business) have their own unique way of handling their traffic over the radio. Aircraft traffic is very formal and precise, since a slight miscommunication can lead to disaster. Almost every word said is repeated by the listener to confirm they received the intended message. They also have code words for certain actions like changing a frequency. Air Traffic Control is very very busy with countless planes in the air. You may hear planes and ATC requesting to change frequency to the next ATC region or to the control tower. The plane won't leave until the ATC says Good Day or Good Night.
So just how do planes way up in the air know where their going? On the ground there are devices called VORs and DMEs. The VORs are like a giant compass on the radio. It sends a different signal for every compass heading and the planes radio picks them up, determines what signal it is and that tells them what direction they are flying to the VOR. Think of a VOR as a huge traffic sign in the sky. A DME (Distance Measuring Equipment) will tell you how far out you are. So with a VOR/DME combined - you know where the VOR is on a map, that tells your heading from the VOR, and the DME tells you how far out from the VOR you are. Now you know right where you are, in the middle of the night at 20,000ft. There are much more intricate systems that use GPS and other devices but the VOR/DME is still the most widely used avionics today. Look on the airport radio map to find the VOR's around Northern California.
Airport Radio is easy to understand if you understand Remote Bases. Basically for Northern California all of Air Traffic Control is based at the "Oakland Center," at the Oakland airport. There are remote bases throughout NorCal that listen on certain freqs and pipe in the traffic via Microwave back to Oakland Center.
