As I’ve been learning my way around PilotEdge I have by necessity been learning my way around the language of Air Traffic Control. One thing I’ve noticed is that sometimes pilots on PE seem to be working hard to sound “official,” whereas what I’ve noticed when listening to the real thing is that real-world pilots (and GA pilots with ATC in particular) are talking an official language but sounding natural (and often, like normal human beings). I’m certain much of that comes with familiarity, and remembering that the controller is, in fact, a person who wants to help you rather than someone waiting for you to screw up.
To that end, here are two resources from the Aircraft Owners and Pilots Association on talking with ATC: their new pilot’s guide to ATC communication, and their PDF document, Communicating With ATC: Learn to Talk Like a Pro. Both are worth reading, as I’m sure that the better you get at knowing the official language, the sooner you’re able to manage it in a familiar and human way.
