Which system is designed to aid ground operations in low visibility conditions?

• A. SMGCS lighting system
• B. ILS navigation system
• C. VOR/DME navigation
• D. GNSS-based landing system

Answer: (A)

In low-visibility ground operations, clear guidance for taxiing and runway movements is essential. The SMGCS lighting system delivers this by coordinating enhanced surface lighting and control tools to guide aircraft and ground vehicles along taxiways and to runways. It uses features like taxiway centerline and edge lights, runway guard lights, lead-on/lead-off lights, and stop bars, all integrated with surface movement radar and air-traffic control to keep movements orderly and safe when visibility is poor. Other options focus on navigation and landing, not on ground movement. ILS and GNSS-based landing systems guide aircraft during approach and landing, not how they taxi on the surface. VOR/DME serves enroute navigation, not surface guidance.
