An ATIS broadcast is identified by ________.

An ATIS broadcast is identified by ________.

• A. Date/time
• B. Number
• C. Airport name
• D. Phonetic letter code

Answer: (D)

ATIS broadcasts are identified by a letter from the phonetic alphabet (for example, Information Alpha, Information Bravo, etc.). This single-letter tag is updated whenever the contained information changes, so pilots and controllers can be sure they’re discussing the same weather, altimeter, active runway, and other variables. When contacting ATC, pilots reference the current information letter to confirm they have the correct data. The other options don’t provide a reliable, unique label: date/time isn’t a stable identifier, the airport name is constant for the airport, and a number could be ambiguous.
