Which term indicates that a previously sent message should be treated as not sent?

• A. Break
• B. Go Ahead
• C. Correction
• D. Disregard

Answer: (D)

Disregard is the instruction to ignore the previous transmission as if it were never sent. In drone and radio command protocols, this cancels any action that would have followed from that message, preventing unintended or unsafe operations. It’s distinct from a correction, which provides updated content to act on, and from Go Ahead, which signals to proceed with the current instruction. Break isn’t about negating a command, but rather pausing or interrupting transmission. So Disregard is the term that tells the receiver not to act on the prior message.
