What three activities are controllers required to perform regarding data?

The correct answer highlights essential cognitive processes that are fundamental to a controller's responsibilities. Controllers must speak clearly to communicate instructions and information to pilots and other personnel. They must also hear attentively to understand the communications from pilots and other control facilities, which is crucial for maintaining situational awareness. Lastly, the requirement to remember is vital, as controllers must retain and accurately recall critical information, such as flight data and instructions, to ensure safety and efficiency in air traffic management.

This combination of listening, speaking, and memory skills underscores the importance of effective communication and information retention in a controller's role. Being able to process verbal exchanges accurately is essential for maintaining the flow of information and for decision-making in high-pressure situations.
