What is the phraseology to use for a pilot requesting immediate raising of the arresting system?

The phraseology "Barrier barrier barrier or cable cable cable" is used in aviation to ensure clarity and urgency when communicating about the arresting system. This specific wording is designed to grab attention and convey the need for an immediate action related to the arresting gear on the runway, such as raising the barrier or cable.

In aviation communications, repeating crucial terms serves to emphasize the importance of the message. The repetition of "barrier" or "cable" is a standard practice to avoid any misunderstanding, especially in high-pressure situations where every second counts, such as during an emergency. This method of communication helps ensure that ground crew and other personnel immediately recognize the urgency and seriousness of the request.

Other phrases might lack this established urgency or clarity. For instance, simply stating "Activate barrier now" or "Raise arresting cable immediately" may not convey the immediate need for action as effectively as the repeated call does. Saying "Proposal for barrier raise" is also less direct and does not carry the same level of urgency required in emergency situations. Therefore, the chosen phraseology effectively communicates the pilot's immediate need and aligns with standard practices in aviation communication.
