Which of the following are examples of clear communication and standardized terminology?

• A. Callouts/code words
• B. CUS words
• C. Go-around
• D. All of the above

Answer: (D)

Clear communication relies on using precise, standardized language so everyone involved shares the same understanding at all times. Callouts or code words provide quick, unambiguous signals about what’s happening or what’s needed, which helps the team track phases of flight and important actions without misunderstanding. CUS words—the concise, standardized terms used to convey safety-critical information—keep messages short and crystal clear, reducing the chance of misinterpretation. A go-around is a formally defined procedure with a specific name and expected steps, so when someone says it, all participants immediately know to abort the approach and execute the missed-approach plan. Taken together, these elements exemplify how standardized terminology and clear communication support safe, coordinated UAS operations.
