At Greenwood ATCT, when does the arrival information need NOT be forwarded during FDIO operation?

In the context of FDIO (Flight Data Input/Output) operations at the Greenwood ATCT, the arrival information does not need to be forwarded when the aircraft sequence remains unchanged. This is because the primary purpose of forwarding arrival information is to ensure that all operational positions have the most current and relevant data about incoming aircraft, especially when there are changes in their sequence or status.

If the sequence of arrivals doesn't change, the existing information is still valid and has already been communicated effectively among controllers. In such cases, there is no need to forward the same information again, as it may lead to unnecessary redundancy and workflow interruptions. Therefore, maintaining a stable sequence allows controllers to work efficiently without continually updating the same data. Understanding this operational efficiency is essential for a smooth coordination of air traffic.

The other options involve scenarios that typically require updates or communications, such as changes in approaches or situations where aircraft are not approaching the airport, which indicates a different handling of data to ensure safety and clear communication among controllers.
