Jason,
The flyers look good. I just found this web site a few minutes ago after googleing SelCal. I read your answer to the earlier question and also went to the link. Both were helpful because I couldn't remember what it stood for and I never realized what the "bing bong" represented.
I am researching CPDLC / FANS1 and when I google it, I come up with articles, but was hoping you might recommend a site that has more basic information on the subject.
If you have a moment, thanks for your help,
