If you are a Pilot, Avionics Engineer, Airline Executive, Mechanic, or maybe just an Aeronautics Enthusiast, ANYONE who is related to aviation has had a "What does this mean?" moment looking at an abbreviation or acronym. Sometimes we see them in a document, others in a chart or a warning display. The point is that when this happens, we may have to search ten or more books to figure out the meaning (if found in any at all) and almost never know where to start. This compilation contains over 10,000 entries originating from all kind of manuals, books, lists, reports, magazines, etc. Obviously...
