When should arrival information be forwarded to a non-approach control tower?

The correct choice emphasizes the importance of timely communication regarding arrival information to ensure efficient traffic management. Forwarding arrival information soon enough allows the non-approach control tower to anticipate incoming traffic and make necessary adjustments to the flow of aircraft on approach. This proactive approach facilitates seamless coordination between different control entities and enhances overall safety and efficiency in the airspace.

This is particularly critical because if the arrival information is not communicated in a timely manner, the tower may be caught off-guard and unable to effectively manage the incoming aircraft. As a result, delays could ensue, potentially leading to increased workload and reduced safety margins during the landing sequence.

In contrast, waiting for a request from the tower or providing information only when the aircraft is on final approach would not allow sufficient time for necessary adjustments, and sharing information during the taxi phase would be too late to influence arrival sequencing. Therefore, timely information is essential for optimal traffic management and safety.
