What does GWO TWR need to inform ZAE of regarding facility status?

The correct answer reflects the need for inter-facility communication regarding operational changes that can significantly impact air traffic management. Specifically, informing ZAE about the change of runway in use and significant weather changes is crucial for several reasons.

Firstly, runways are vital components for takeoffs and landings, and any change in their operational status can affect flight operations and safety. For instance, if one runway is closed for maintenance or is unsuitable due to adverse weather conditions, aircraft must be rerouted to alternate runways. This information allows air traffic controllers to make informed decisions on aircraft sequencing and manage traffic flows efficiently.

Secondly, significant weather changes can drastically affect operations at an airport. If there’s a sudden onset of adverse weather, such as heavy rain, snow, or fog, it can impact visibility and runway conditions, necessitating immediate relay of this information to ensure the safety and efficiency of air traffic.

While operational hours, scheduled maintenance, and fuel replenishment are important, they do not have the same immediate and critical impact on flight operations as changes in runway usage and significant weather updates. Thus, the focus on runway changes and weather conditions is paramount in ensuring safety and efficient control of air traffic.
