What is the proper radio acknowledgement when you have heard a transmission and will comply?

• A. Copy
• B. Wilco
• C. Roger
• D. Affirmative

Answer: (B)

When you hear a directive and you will carry it out, you use Wilco. It signals that you received the transmission and you are committed to complying with the instruction. This is different from saying Roger, which only confirms you heard the message, or Copy, which means you understood but doesn’t promise action. Affirmative is just a yes to a question and doesn’t convey that you intend to perform the requested action. So Wilco is the best fit here because it communicates both receipt and intent to comply.
