What is the role of surveillance displays in the ATC automation chain?

• A. To show weather charts to pilots
• B. To display real-time radar/ADS-B surveillance for controllers
• C. To schedule flights
• D. To handle vehicle traffic on the ground

Answer: (B)

Surveillance displays provide the controller with a real-time picture of where aircraft are, using radar and ADS-B data. In the automation chain, these data are collected, validated, and fused into tracks that include position, altitude, speed, and identity, which are then shown on the displays. This live view lets the controller monitor all traffic, assess potential conflicts, maintain safe separations, and coordinate handoffs and clearances as air traffic evolves. Weather charts for pilots are separate briefing or in-flight weather products, not the controller’s surveillance view. Scheduling flights belongs to planning and operations systems, not live surveillance monitoring. Ground vehicle traffic uses its own surface movement tools and displays, which handle airport surface coordination rather than en route or terminal airspace surveillance.
