How NatoSpellBase works
Last updated July 21, 2026
Letter mapping follows the international radiotelephony spelling alphabet (ICAO), commonly searched as the NATO phonetic alphabet. We use Alfa (not Alpha), Juliett (two t's), and X-ray.
Spelling tools map A–Z characters in your input to code words and join them for copy. Other characters are skipped. Optional browser speech synthesis may read a selected word or the full spell strip — that is a convenience voice, not an official ATC recording.
Quizzes draw randomly from the same 26-word list. Scores stay in the session; nothing is uploaded for grading.
