What is the correct process for making corrections to a message during transmission?

The process for making corrections to a message during transmission requires clarity and precision to ensure that the receiver understands the intended information. Saying "CORRECTION" followed by the last correct version and then the corrected message effectively communicates that there has been an error in the preceding transmission and provides the corrected information in a clear and structured manner. This method allows the recipient to easily identify and comprehend the mistake without confusion.

Using "CORRECTION" establishes a clear marker that a mistake has occurred and that the subsequent information is to replace the previous details. This practice is crucial in aeronautical communication where mistaken information can lead to misunderstandings or errors that may have significant implications.

While other options might suggest ways to clarify an error, they don't provide the structured approach needed in formal aviation communications. For instance, simply saying "ERROR" followed by the last word does not effectively indicate what needs to be corrected or what the correct information is. Transmitting the message again without any clarification lacks the necessary context for the receiver to understand what has changed. Using "RETRANSMIT" and resubmitting the entire message does not specifically highlight what part is corrected, which can lead to additional confusion. Thus, the structured approach of a correction followed by the correct information is
