Which radar type guides aircraft during landing when visibility is near zero?

• A. Weather radar
• B. Approach radar
• C. Navigation radar
• D. Ground radar

Answer: (B)

Guidance on final approach and landing in very low visibility relies on a system that lets the controller see the aircraft’s position and guide it onto the correct approach path. Approach radar is designed for this purpose, providing the controller with real-time information on an aircraft’s bearing and range to the runway and allowing them to vector the aircraft to the final approach. This supports a precise, safe landing when pilots’ outside visibility is minimal. Weather radar is for detecting precipitation, not guiding an approach. Navigation radar covers broader navigational awareness rather than the specific landing path. Ground radar tracks aircraft on the airport surface, not while airborne on approach.
