What must GWO TWR communicate prior to changing runway in use?

The correct answer pertains to the requirement for Ground Operations Tower (GWO TWR) to communicate the runway in use before a change occurs. This is crucial for multiple reasons. First, communicating the current runway ensures that all aircraft in the vicinity, including those in the approach phase and on the ground, are aware of which runway is active for takeoffs and landings. This minimizes the risk of confusion among pilots and ground personnel, allowing for safer and more efficient operations.

This communication is vital for maintaining situational awareness and ensuring that air traffic control procedures are followed correctly. When the runway in use is clearly communicated, it assists in coordinating traffic flow, managing inbound and outbound flights effectively, and preventing potential conflicts on parallel runways or taxiways.

In contrast, while other options, such as communicating weather statuses or expected delays, are important aspects of air traffic management, they do not directly address the immediate need for clarity regarding the runway in use during a change. Similarly, a maintenance schedule for runways is specific information that may not be directly related to the operational status required at that moment. Therefore, emphasizing the runway in use is fundamental to ensuring safety and efficiency in air traffic operations.
