Private Jet Charter Q & A Week 4: What is the aviation alphabet?

Aviation Alpha Bet

As a frequent jet charter flyer, you’ve probably experienced a time when your charter pilots were speaking as if in a foreign language.  From the cockpit, you may have overheard your pilots saying something like: Tower, this is Citation-Five-Two-Five-Charlie-Juliet, ready to taxi to the active or Gulfstream-One-Two-Three-Papa, clear for takeoff, runway one-three. Although, this odd string of words and numbers may have seemed strange to you at the time, the words Charlie,Juliet, and Papa, are apart of the official aviation alphabet used regularly in private aviation. The aviation alphabet, first introduced by the International Civil Aviation Organization in 1956, was designed to help pilots and controllers communicate more effectively while talking over the radio.

How the Aviation Alphabet Works:

The aviation alphabet, or speaking alphabet consists of 26 different code words; one word for every letter of the alphabet.  The aviation alphabet begins with the word Alpha (the code word for the letter A) and continues all the way through to Zulu (the code word for the letter Z). The aviation alphabet is used primarily to spell out parts of a message that contain similar sounding letters, such as “n” and “m” and “b” and “c”, that can confuse pilots and controllers when spoken over the radio. To eliminate the confusion caused by similar sounding letters, pilots and controllers rely on the use of the aviation alphabet to speak private aircraft numbers, airports, runways and taxiways.  For example, pilots use the aviation alphabet to spell out airport identifiers to avoid sounding like other airports.  Just imagine if your charter flight to Teterboro, New Jersey (KTEB) was rerouted to Detroit, Michigan because your controllers thought your pilots said D-E-T instead of T-E-B. Using the alphabet, pilots would ask controllers for vectors, or navigation, to Tango-Echo-Bravo instead to ensure the message is received clearly. The aviation alphabet is also primarily used to spell out private aircraft identification numbers.  Have you ever wondered why your private jet is referred to as November-One-Two-Three-Echo-Romeo instead of N-One-Two-Three-E-R? That’s your aircraft’s identification or tail number according to the aviation alphabet.  Your charter pilot will always refer to your aircraft using the aviation alphabet when communicating to other pilots and controllers.  This helps air traffic controllers know which aircraft they are communicating with over the radio. The aviation alphabet is extremely important to private aviation safety because it helps pilots and controllers communicate in the most effective way possible.  This will increase your pilots situational awareness and increase your level of air charter safety for your flight.  Below is the full list of words used in the aviation alphabet.  By memorizing the entire alphabet, you may just be able to impress your charter pilot the next time you fly.
