Which RADAR is used to guide aircraft to a safe landing in zero visibility conditions?

• A. Approach RADAR
• B. Surface-Search RADAR
• C. Airborne RADAR
• D. Missile RADAR

Answer: (A)

When visibility is zero, guiding the aircraft from approach to touchdown relies on a ground-based radar system that provides real-time position information to the controller and allows precise instructions to steer the aircraft along the correct approach path. Approach radar does exactly this in the terminal area: it tracks inbound airplanes and helps the controller vector them, maintain proper spacing, and lead them to the final approach, which is essential for a safe landing when the pilot cannot rely on visual cues. Surface-search radar looks for objects on the ground and isn’t used for guiding a landing. Airborne radar is mounted on the aircraft and serves on-board navigation and weather detection, not ground-based approach guidance. Missile radar is for tracking weapons and isn’t involved in civilian landing procedures.
