Which system provides surface movement guidance and surveillance to help pilots and drivers navigate the airfield?

• A. Instrument Landing System (ILS)
• B. Airfield lighting and signage, along with surface movement radar/ASDE systems.
• C. Meteorological Data Exchange System
• D. Aircraft Maintenance Tracking System

Answer: (B)

Guidance and surveillance on the airfield come from a combination of visual cues and ground tracking. Airfield lighting and signage give clear visual directions for where to taxi, hold, or cross runways, helping pilots and ground vehicles navigate safely, especially in low visibility or at night. Surface movement radar, or ASDE, provides real-time detection and tracking of aircraft and vehicles on the ground, so controllers can monitor movements, coordinate sequencing, and prevent collisions.

This pairing is what enables safe, efficient ground operations. The other options don’t fit because ILS guides approaches and landings, not ground movement; meteorological data exchange deals with weather information; and aircraft maintenance tracking handles maintenance records.
