What is the primary benefit of integrating ground-based radar with ATC surveillance?

• A. Improved separation and sequencing
• B. Increased weather detail
• C. Reduced need for ground radar
• D. Longer data latency

Answer: (A)

Integrating ground-based radar with ATC surveillance gives controllers a single, coherent, real-time view of aircraft positions and movements. This richer, timely picture lets you maintain safe horizontal and vertical separation more reliably and sequence arrivals and departures more efficiently. With improved tracking accuracy and faster conflict detection, air traffic can flow smoothly, even in busy sectors. Weather radar provides weather information, but that’s a separate capability; the primary benefit of integration here is enhanced awareness and control of aircraft positions for safer, more efficient sequencing. Longer data latency would reduce safety and efficiency, and this integration does not eliminate the need for ground radar.
