When communicating on the radio, what type of language should be avoided?

Using abbreviations and slang should be avoided when communicating on the radio because it can lead to misunderstandings and confusion. Clear communication is essential in aviation, where even a small miscommunication can have serious consequences. Radio communications are often monitored by various parties, including air traffic control, other pilots, and ground crews, so clarity is vital for everyone involved to accurately interpret the messages being conveyed.

Technical jargon may be used appropriately among pilots who are familiar with the terms; however, using commonly understood language is best when addressing a mixed audience. Clear and concise language is encouraged to ensure that all instructions and information are easily understood. Phonetic spelling is also recommended for clarity, particularly for spelling out names or identifiers over the radio, minimizing the chance of misinterpretation.
