Which of the following is not a function of the ATCSCC?

The answer is based on the distinct role of the Air Traffic Control System Command Center (ATCSCC) within the broader air traffic management framework. The ATCSCC is primarily tasked with coordinating and managing air traffic flow on a national level. This involves analyzing traffic patterns, overseeing the implementation of traffic management initiatives, and optimizing the use of airspace to ensure safe and efficient movement of aircraft.

Managing traffic at individual airports falls under the functions of Air Traffic Control (ATC) towers, which are responsible for directing aircraft within the vicinity of an airport and during takeoff and landing. These towers focus on localized traffic management, while the ATCSCC operates on a larger scale, coordinating efforts across multiple sectors and regions to improve overall air traffic efficiency.

In summary, the ATCSCC coordinates air traffic flow and implements traffic management initiatives, but it does not directly manage traffic at individual airports, which is why that choice is not a function of the ATCSCC.
