How do controllers use weather radar overlays and ground-based radar in traffic management?

• A. Ground radar monitors movement and positions
• B. Weather radar identifies convective hazards and advisories; controllers adjust routing
• C. Weather radar is used only for turbulence reports
• D. Ground radar monitors runway lighting

Answer: (B)

Weather radar overlays let controllers see where convective weather is forming and moving, layered on the airspace display along with aircraft positions. This real-time picture lets them gauge hazard areas, trend how storms might evolve, and anticipate where aircraft might be affected. In traffic management, that information drives action. If a storm cell is headed toward a flight path or a terminal approach corridor, controllers issue advisories and adjust routes to keep aircraft clear of the hazardous weather. They can vector aircraft around the cell, assign different altitudes or speeds to maintain safe separation as weather shifts, and implement routing or flow adjustments to keep traffic moving safely and efficiently. The goal is to minimize exposure to convective hazards while preserving orderly, efficient traffic flow. Ground-based radar complements this by providing accurate position data for aircraft and ground movements, which is essential for maintaining separation and sequencing as weather decisions are made. It tracks where aircraft are and where they’re going, independent of weather data. The other options don’t capture the full purpose: one describes monitoring movement without addressing weather hazards; another overly narrows weather radar to turbulence reports; and another wrongly ties ground radar to runway lighting.
