This is an excellent book to familiarize yourself with air traffic control and tower talk. I'm a private pilot and I learned in a relatively low trafficked area in Maine. The Portland tower was nearby but I didn't take advantage of it too much. I read the book one summer while I was still a student pilot . . . when I went up with an instructor and we headed to a towered airport he was very impressed on how I knew how to call them up and respond to them, I understood the flow of frequency changes well, and understood all the instructions I received from ATC before he ever taught me any of that stuff. Even if you are already a pilot, but still avoid going to towered airports because you're afraid of getting embarassed you should most definitely get this book.
The actual examples he gives are right on the money. The good part is that he give you variations on how to say the same thing so in case you hear it differently from someone you'll be ready. I don't really have any complaints with this book that I can think of at the moment. It's helpful to VFR student, and actual pilots, it has realistic examples, good explanation of why things are the way they are with ATC, explains the ATC environment well. Get it!
