It looks like this will be addressed on the ATC side. Starting 9/19/08 the "Cactus" 3 letter ID will be AWE. USA will no longer be used. It's like one of those timed brain games where they show you the word BLUE and the print is red and the question is "What color is the word?" There was a lot of room for error. Now if we can get the pilots to play along.
