Radio etiquette: There should not be another pilot speaking on the radio before making your transmission.

• A. Before
• B. During
• C. After
• D. While

Answer: (A)

Listening before transmitting is essential on shared radio frequencies. In drone operations and aviation, you wait for the channel to be clear so you don’t interrupt another pilot’s transmission and so your message comes through reliably. Completing the sentence with the word that fits best conveys this timing: there should not be another pilot speaking on the radio before making your transmission. In practice, you listen for a pause and then proceed with your call sign and message, ensuring orderly, unoverlapped communication. The other options don’t capture that waiting-for-a-clear-channel timing and would imply speaking at the wrong moment.
