Which code word represents the letter X?

Which code word represents the letter X?

• A. Yankee
• B. Zulu
• C. X-ray
• D. Romeo

Answer: (C)

In aviation communications, the NATO phonetic alphabet is used so letters come across clearly over the radio, even in noisy conditions. Each letter has a unique code word, and for the letter X, that word is X-ray. This choice makes the letter unmistakable when spoken, reducing confusion with similar sounds like “eks” or other letters during critical instructions or flight plans. Other code words you might hear refer to different letters—for example, Yankee represents Y, Zulu represents Z, and Romeo represents R—so they do not designate X. Remembering that X-ray is the code word for X helps ensure precise and safe communication when spelling out callsigns, waypoints, or coordinates.
