Center/ARTCC is primarily responsible for which duty?

• A. En-route control across large regions, high-altitude traffic, and inter-sector handoffs
• B. Tower surface operations
• C. Terminal arrivals sequencing
• D. Weather reporting

Answer: (A)

The main thing this item tests is the scope of responsibilities for ARTCCs. Centers handle en-route control across large regions, guiding high-altitude traffic as aircraft cruise and coordinating handoffs between adjacent sectors and centers to maintain separation and flow. This is distinct from the duties of a tower, which manages ground movement and local operations at an airport, and from terminal arrivals sequencing, which is handled by approach/arrival facilities (TRACON) as aircraft descend into busy terminal areas. Weather reporting is provided by meteorological services and shared data used by controllers, not a primary duty of the center.
