What does the Surface Movement Guidance and Control System (SMGCS) pertain to during inspections?

The Surface Movement Guidance and Control System (SMGCS) is specifically designed to enhance the safety of aircraft movements on the airport surface, particularly in conditions of reduced visibility. Checking the lighting system and its operability is a critical component of ensuring that the SMGCS functions correctly, as the system relies on effective lighting to guide pilots safely during taxiing and other ground movements. Proper visibility is vital to prevent accidents and enhance situational awareness, which makes the inspection of the lighting system essential.

In contrast, other options like evaluating runway capacity, monitoring weather conditions, and inspecting passenger facilities, while important for overall airport operations, are not directly related to the primary focus of SMGCS, which is to provide guidance and control for surface movement.
