In what situation should the Administrative Work Station (AWS) be used?

The Administrative Work Station (AWS) is specifically designed to assist in managing and distributing payload for flights that are entering a hub airport or between hub airports. Using AWS in these situations allows for more efficient handling of flight data, weight and balance calculations, and overall load management, which is crucial for maintaining safety and adherence to operational procedures.

When flights operate into a hub city or between hubs, the AWS can process essential information regarding passenger and cargo distribution, leading to optimized aircraft performance and enhanced operational efficiency. This is particularly important as hub cities often have higher traffic volumes and complexities that necessitate precise management of payload distribution.

While other options may imply specific circumstances for the use of AWS, they do not encompass the broad applicability required for maintaining optimal operations in both hub city arrivals and hub-to-hub travels, which makes the given answer the most suitable choice in this scenario.
