How must a ground controller advise the local controller when the coordinated runway operation is complete?

The process of notifying the local controller that the coordinated runway operation is complete can be effectively accomplished through verbal communication or visual aids. This approach ensures clarity and allows for immediate confirmation or questions if anything is unclear. Verbal communication is often the most reliable and direct method of conveying such time-sensitive information. Additionally, using visual aids can support understanding and reinforce what is being communicated verbally, helping both controllers maintain situational awareness.

In contrast, relying solely on automated alerts may not provide the necessary context or immediacy required in busy terminal operations, where human oversight can enhance safety and efficiency. Depending exclusively on radio communication may limit the effectiveness of communication if, for example, transmission issues occur or if the information needs to be conveyed quickly in a dynamic environment. Written directives, while useful for record-keeping, are not practical for immediate, real-time communication and decision-making during coordinated runway operations.
