When should you forward arrival information to a non-approach control tower?

Forwarding arrival information to a non-approach control tower is crucial for maintaining efficient traffic flow and safety. By sending this information soon enough to permit adjustments to the traffic flow, the tower can effectively manage arriving aircraft and coordinate their landings. This proactive communication allows the tower to prepare for incoming flights, ensuring that they have the necessary situational awareness to make timely decisions regarding spacing, sequencing, and landing priorities.

This approach helps prevent congestion and allows controllers to better manage resources such as runways and taxiways. It enhances situational awareness for both the arriving aircraft and the tower, facilitating a smoother transition from the en-route phase to the landing phase.

The other choices do not effectively address the timing and nature of forwarding arrival information. Immediate forwarding upon departure may not provide sufficient time for the tower to adjust its operations, while a stipulation based solely on altitude or waiting for pilot instruction does not ensure proactive management of traffic flow.
