Nasa Alphabet Chart

Understanding the Nasa Alphabet

This page covers the “Nasa alphabet” A–Z radio spelling words (for example, A = Alpha, B = Bravo, C = Charlie).

This same set is widely known as the NATO phonetic alphabet. People use it in aviation, military, emergency services, and radio communication to avoid letter confusion.

Use the chart to memorize the mapping and practice spelling real words out loud using the code words.

How to Use Code Words

When spelling, say one code word per letter. Example: “CAT” becomes “Charlie Alpha Tango”.

Speak at a steady pace and pause slightly between words. Clarity matters more than speed.

If someone repeats a letter back incorrectly, re-send that letter using the code word again rather than just repeating the single letter name.

Pronunciation Tips

Treat the code words as fixed labels. Many are familiar English words, but the important part is using the standard set consistently.

Some words have conventional spellings like “Juliett” and “X-ray”. Keep those forms as shown on the chart.

Practice with real scenarios: spelling names, email addresses, serial numbers, and short identifiers.

Learning Tips

Learn in chunks: A–F, G–L, M–R, S–Z. Review daily until recall is instant.

Do fast drills: point at a random letter and say the code word, then reverse (hear a code word and write the letter).

Focus extra practice on easily confused pairs (for example: M/N, B/D, P/T, F/S).

Practice With Downloads

Use the PDF and image as clean references you can print or keep offline. The worksheet helps with repetition practice while keeping the code words visible.

Pick a small set today, practice them well, and expand gradually. Speed comes naturally once recall is automatic.
