Which of the following is not a basic element of the Standard Terminal Automation Replacement System (STARS)?

The Standard Terminal Automation Replacement System (STARS) consists of several integral components designed to enhance air traffic management and support operations at terminal areas. Among the various components, the STARS Central Operational Site (SCOS) is not recognized as a basic element of the system.

The primary components typically include facilities like the STARS Operational Site (SOS) and the Operational Support Facility (OSF), which play crucial roles in the system's functionality, ensuring that air traffic controllers have the tools necessary for effective airspace management. The STARS Central Support Complex (SCSC) serves a supportive and operational function, assisting in the maintenance and administration of the system.

In contrast, the SCOS is not a standard designation within the framework of STARS, and recognizing this helps clarify the structure and terminology used in air traffic control systems. Understanding these distinctions is essential for grasping the organization and operation of various components in air traffic technology.
