How should the aircraft call sign N169US be spoken phonetically?

• A. November one six niner uniform sierra.
• B. November one six nine uniform sierra.
• C. November six one six nine uniform Sierra.
• D. November one six niner uniform zulu.

Answer: (A)

The key idea is using the standard radiotelephony spelling: the registration is spoken by saying the ICAO phonetic equivalents for letters and the digits spoken individually, with 9 uniquely pronounced as “niner.” For a US registration starting with N, you say the prefix as November, then each digit as a word, and the remaining letters as their phonetic words. So 1 is one, 6 is six, and 9 is niner, followed by U as Uniform and S as Sierra. Put together, the correct spoken form is: November one six niner uniform sierra. This avoids common pitfalls. Some options use “nine” instead of “niner,” which isn’t the standard radiotelephony form. Others mix up the digit order or misstate the last letters (using zulu or not using the correct phonetics for U and S).
