Which term is used to acknowledge receipt and understanding of the last instruction?

• A. Out
• B. Over
• C. Roger
• D. Read Back

Answer: (C)

In radio communications, the phrase you use to acknowledge receipt and understanding of the last instruction is the one that signals you heard and understood what was said. That term conveys, simply, comprehension of the message. It doesn’t promise action or indicate that the channel will stay open—those nuances are expressed with other phrases. For example, if you intend to act on the instruction, you’d use a term meaning you will comply; if you’re finished transmitting, you’d say you’re leaving the air; if you need the instruction repeated to confirm accuracy, you’d request a read-back. Using the correct acknowledgment keeps exchanges clear and reduces the chance of miscommunication during operations.
