Welcome aboard this in-depth guide on how to say numbers in aviation! Whether you are a seasoned pilot, an aspiring aviator, or simply fascinated by the world of aviation, understanding the proper pronunciation of numbers is crucial for effective communication in the skies. In this guide, we will explore both the formal and informal ways of saying numbers, providing useful tips, examples, and explanations along the way. So, let’s dive right in!

Formal Pronunciation of Numbers
When it comes to formal communication in aviation, precision, clarity, and consistency are paramount. To ensure seamless understanding between pilots, air traffic controllers, and other aviation personnel, the International Civil Aviation Organization (ICAO) has established standard pronunciation guidelines for numbers up to 9999. These standards, known as the Radiotelephony Spelling Alphabet, are used globally and are especially crucial for exchanging flight details, clearances, altimeter settings, and other numerical information.
The Radiotelephony Spelling Alphabet
The Radiotelephony Spelling Alphabet replaces digits with unique words to minimize potential confusion caused by similar-sounding numbers. Here is a list of the corresponding words for each digit:
- 0 (Zero) – Ze-ro
- 1 (One) – Wun
- 2 (Two) – Too
- 3 (Three) – Tree
- 4 (Four) – Fow-er
- 5 (Five) – Fife
- 6 (Six) – Six
- 7 (Seven) – Sev-en
- 8 (Eight) – Ait
- 9 (Nine) – Niner
Using the Radiotelephony Spelling Alphabet ensures that numbers are communicated clearly, even in adverse conditions or amid various accents. For example, the altitude 2500 feet will be communicated as “Too Fife Zero Zero Feet” rather than “Two Five Zero Zero Feet.”
Examples of Formal Pronunciation in Aviation
Let’s look at some examples to see the Radiotelephony Spelling Alphabet in action:
- Flight Level 350 – “Flight Level Tree Fife Zero”
- VOR Frequency 112.1 MHz – “VOR Freqwency Wun Wun Too Point Wun Megahertz”
- Runway Heading 270 – “Runway Heading Too Seven Zero”
- Flight Level Transition 5000 – “Flight Level Transition Fife Zero Zero Zero”
By adhering to the Radiotelephony Spelling Alphabet, pilots, air traffic controllers, and other aviation professionals can ensure precise and consistent communication, leaving no room for misinterpretation.
Informal Pronunciation of Numbers
In less formal scenarios, such as when communicating within the cockpit or engaging in non-essential conversations, pilots may occasionally use a less rigid approach to pronounce numbers. While it is still essential to maintain clarity, informality allows for a more relaxed and faster exchange of information.
When it comes to informal pronunciation, pilots often adopt a more natural way of saying numbers, as they would in everyday speech. Here are some tips to keep in mind:
- 1. Use Single-Digit Pronunciations: Instead of saying “Wun Two Three,” simply say “One Two Three.”
- 2. Drop the Zero: Eliminate the word “Zero” when it precedes the number when reading altitudes. For example, say “Two Fife Zero Zero Feet” as “Two Fife Hundred Feet.”
- 3. Use Ordinary Decimals: Rather than using the formal “Point,” say “Dot” when pronouncing decimal numbers. For instance, say “One Wun Two Point Five” as “One One Two Dot Five.”
- 4. Natural Rhythm: Follow the rhythm and flow of speech, emphasizing certain syllables without sacrificing clarity. This helps maintain a smooth exchange of information.
Examples of Informal Pronunciation in Aviation
Let’s take a look at some examples to illustrate the differences between formal and informal pronunciation:
- Heading 090 – “Heading Zero Niner Zero” (formal) / “Heading Niner Zero” (informal)
- Altitude 3800 feet – “AltiTree Eight Zero Zero Feet” (formal) / “AltiThree Eight Zero Zero Feet” (informal)
- VOR Frequency 114.3 MHz – “VOR Freqwency Wun Wun Fow-er Point Tree Megahertz” (formal) / “VOR Freqwency One One Four Dot Tree Megahertz” (informal)
Remember, while informality can be used during non-critical communications, it is essential to quickly switch back to precision and formality as the situation demands.
Final Words
Mastering the art of saying numbers in aviation is an essential skill for effective communication and safe flight operations. By following the formal pronunciation guidelines using the Radiotelephony Spelling Alphabet, pilots and aviation professionals ensure precise and consistent exchanges even in adverse conditions. Meanwhile, embracing informality during non-essential communications allows for a more relaxed and efficient exchange of information. Remember to adapt your pronunciation style based on the context and prioritize clarity, accuracy, and maintaining a warm and professional tone throughout.
Clear and accurate communication is the key to successful aviation, and mastery of number pronunciation is an integral part of that equation.
