Which lighting system provides visual guidance during landing operations at night and under low visibility?

• A. Sign Lighting
• B. Approach Lights
• C. Taxiway Lights
• D. Runway Lights

Answer: (B)

Approach lighting provides the visual cues pilots need to find and align with the runway during the final approach, especially at night or in low visibility. This system sits at the end of the runway and extends outward along the approach path, often with sequenced flashing lights and crossbars that help the pilot gauge distance to the threshold and maintain the proper glide path. By giving a clear visual corridor toward the runway, it supports transitioning from instrument-only guidance to visible cues as the aircraft gets closer to landing. Runway lights illuminate the runway surface once it’s in view, taxiway lights guide movement on the ground between areas, and sign lighting helps read on-ground signs. But the approach lighting system is specifically designed to guide the aircraft during the approach phase in reduced visibility.
