What is the area of coverage for the Standard Terminal Automation Replacement System (STARS)?

The Standard Terminal Automation Replacement System (STARS) is designed to enhance the efficiency of air traffic control operations, particularly in terminal airspace. The area of coverage for STARS is specifically 400 nautical miles in diameter, which can be understood as a coverage range extending 200 nautical miles from the center point in all directions. This extensive coverage allows STARS to effectively manage terminal airspace around busy airports, improving safety and coordination among aircraft during takeoff and landing phases.

Understanding the dimensions of the system's coverage is critical for air traffic controllers and operational planners, as this determines the system's capability to support high volume traffic and ensure precise management of arriving and departing flights. The other options do not accurately reflect the measured operational range of STARS, reinforcing why 400 by 400 is the appropriate selection for defining this system's coverage area.
