When should arrival information be forwarded to a VFR Tower?

The correct response indicates that arrival information should be forwarded to a VFR Tower soon enough to allow for the adjustment of traffic flow. This timing is crucial in ensuring that the tower can effectively manage incoming and outgoing traffic, particularly in busy airspace where coordination is essential for maintaining safety and efficiency.

By sending arrival information in a timely manner, controllers enable the tower to make necessary adjustments to sequencing and spacing of aircraft. This can involve pushing or holding departures, adjusting landing clearances, and preparing for any potential conflicts with other traffic in the terminal area. Effective management of traffic flow contributes to safer operations and reduces the likelihood of delays or issues as aircraft arrive at the airport.

In contrast, forwarding information immediately upon arrival, within 10 minutes prior to landing, or only once the aircraft is on final approach does not allow sufficient time for the tower to adjust and coordinate appropriately. These options could lead to rushed decisions and potential congestion or conflicts in traffic, which is why they do not align with standard practices in air traffic control.
