When must data be forwarded to GWO TWR when FDIO is operational?

The requirement to forward data to GWO TWR when FDIO (Flight Data Input/Output) is operational is critical for maintaining situational awareness and ensuring safe and efficient air traffic management. The correct answer highlights that data must be updated and forwarded to GWO TWR whenever there is a change in the sequence of aircraft or when an approach is issued.

This is crucial because changes in the sequence can significantly impact the flow of aircraft in and out of controlled airspace. If a new approach is issued, it implies that an aircraft might be directed to change its course, altitude, or other parameters, which requires timely communication to the tower for coordination purposes. This ensures that GWO TWR has the most current flight data, which is essential for making informed decisions that affect the safety and efficiency of air traffic.

Other options lack the timeliness or relevance necessary for competitive air traffic management. For instance, changing the flight plan or requesting a fly-over may be important, but they do not inherently necessitate immediate updates to the sequence of aircraft or approaches being conducted. Furthermore, forwarding data only at the beginning of operations would miss ongoing updates that are vital throughout the day. This understanding is why maintaining accurate and real-time data transfers to GWO TWR is
