The Aviation Alphabet is another name for the ICAO spelling alphabet that is specifically used at commercial airports in the US and abroad. Airports in the US that service many flights with Delta Airlines use alternatives for the letter D, such as “Data,” “Dixie,” or “David,” instead of the word “Delta” to avoid confusion with Delta pilots.
