What is the standard way to indicate you are ready for further instructions?

• A. Stand by and wait for further instructions.
• B. Say 'Roger' to indicate readiness.
• C. Keep transmitting until acknowledged.
• D. Say 'Over' to indicate you are ready for the controller's next instruction.

Answer: (D)

In radio communications, clear turn-taking uses specific phrases to signal what happens next. Saying “Over” shows you’ve finished your transmission and are ready for the controller’s next instruction. It prompts the other station to reply and continue the exchange.

“Roger” only confirms you received the previous message; it doesn’t indicate you’re waiting for more instructions. “Stand by” can mean to pause, but it doesn’t explicitly request the controller’s next action. Keeping transmissions going until someone acknowledges isn’t proper radio etiquette and can clog the channel. So the standard way to indicate you’re ready for further instructions is to say “Over.”
