For CAT III operations below 1200 ft RVR, what must the airport establish for taxiing aircraft safely from parking to the runway?

For CAT III operations below 1200 ft RVR, what must the airport establish for taxiing aircraft safely from parking to the runway?

• A. Glideslope (GS)
• B. Localizer (LOC)
• C. Surface Management Guidance Control System
• D. Very High Frequency Omnidirectional Range (VOR)

Answer: (C)

In CAT III operations with visibility very low (below 1200 ft RVR), the key need is reliable guidance and monitoring of aircraft as they move on the surface to reach the runway without confusion or incursions. The airport must establish a Surface Management Guidance and Control System (SMGCS), which provides real-time guidance, surveillance, and coordination for ground movements. It integrates surface movement radar, enhanced taxiway lighting and signage, and clear ATC procedures to route and track taxiing aircraft safely in low visibility. Glideslope and localizer are for approaches to the runway, not for steering aircraft on the ground, and a VOR is an enroute navigation aid, not a ground taxi guidance system. SMGCS directly addresses the need to manage taxiing safely under low visibility conditions.
