Phonetic Alphabet and Numbers
In aviation, the Phonetic Alphabet, also known as the International Civil Aviation Organization (ICAO) alphabet, is a standardized set of words used to represent letters. This system is designed to minimize confusion during radio communication, particularly when dealing with similar-sounding letters or when the message needs to be conveyed with utmost clarity. Pilots and air traffic controllers rely on this phonetic language to ensure accurate transmission of information.
In the early days of radio communication, everyone was analogue and not nearly as clear as modern day communication. For that reason, a system had to be deviced to eliminate ambiguity as much as possible.
Example the letter C…..
Charlie Tango, if pronounced as the usual CT, could be mistaken for CC or TT over the radio, that is why the phonetic alphabets are used

Each word represents a specific letter, and this alphabet is widely used in aviation, military, and other contexts where clear and unambiguous communication is crucial.
Here are ten popular phrases used by pilots and air traffic controllers using the Phonetic Alphabet:

the letter ‘B.’
“Charlie” (C):
Example: “Charlie Tango 789, descend to 10,000 feet.”
Used to represent the letter ‘C,’ this phrase aids in clear communication during altitude assignments or any instructions involving numerical values.
“Delta” (D):
Example: “Delta Echo 234, expect vectors for ILS approach.”
Indicates the letter ‘D’ and is often used in route clearances or when referencing specific waypoints.
“Echo” (E):
