Final answer:
SMGCS is a system designed to safely guide aircraft on the ground during low visibility conditions. It helps airfield operations by providing clear guidance to pilots, preventing runway incursions, and improving ATC's visibility of airport surface movements.
Step-by-step explanation:
SMGCS, or Surface Movement Guidance and Control System, is a system designed to facilitate the safe and efficient movement of aircraft on the ground during periods of low visibility conditions. This system is essential for airfield operations, particularly during inclement weather or at night when visibility is reduced.
The SMGCS helps airfield operations in multiple ways. Firstly, it provides clear guidance to pilots on the ground in terms of taxi routes, holding positions, and other ground operations, through a combination of markings, lighting and signage. Secondly, it helps prevent runway incursions, which are situations where an unauthorized aircraft, vehicle, or person is on a runway. This is done by clear demarcation and control of taxiways and runways, and by providing realtime surveillance and control of all ground movements. Additionally, it also provides ATC (Air Traffic Control) with improved visibility of the airport surface movement.
