Al,
you keep making general statements about the NAS airspace classifications that when we get down to the specifics are either wrong or partially wrong. When we proved to you how easy it was to find the geographic center of an airport you then want to argue that the FAA "may" not use the same definition. Are you serious?
Do you have any problems with the form letter that I provided as the OP of this thread? Use it, don't use it I don't care.
