Which terms should never be used over the radio unless accompanied by the phrase 'loud and clear' during a radio check?

• A. taxi, hold, go
• B. roger
• C. affirmative
• D. clear, cleared, or clearance

Answer: (D)

When testing radio reliability, you confirm you can hear and understand the other person by saying “loud and clear.” The words clear, cleared, or clearance are actual clearance or instruction terms in radio language. If you use them without the safety net of “loud and clear,” they can be misinterpreted as issuing or receiving a real clearance rather than just testing the link, which could lead to unsafe actions or confusion. So those terms should not be spoken during a radio check unless you add “loud and clear” to show you’ve successfully heard and understood.
