Which of the following is NOT a component of the Air Traffic Control System?

The choice identifying passenger services as not a component of the Air Traffic Control System is accurate because passenger services pertain more to the operations and facilities that facilitate passenger travel rather than the core functions of air traffic control. The Air Traffic Control System primarily focuses on safety, efficiency, and management of air traffic, which is critical for guiding aircraft during flights and ensuring that airways are clear.

The main components of the system include personnel, who are the air traffic controllers and support staff managing the airspace; technological infrastructure, which encompasses radar systems, communication equipment, and navigation aids; and procedures, which are established protocols and practices that govern how air traffic is controlled. While passenger services are essential for airlines and airport operations, they fall outside the scope of what air traffic control is designed to handle.
