An A-SMGCS system involves many different functionalities which contribute to support the safe, orderly movement of aircraft and vehicles on airfields. The A-SMGCS system also takes into consideration the circumstances with respect to the density of traffic, the complexity of the airport layout, and considering the demanded capacity under various visibility conditions, independent of line-of-sight connection between the controller and aircraft or vehicles.
The A-SMGCS is more than just different hardware systems working in conjunction with each other. It includes working procedures and at the lower levels aims to deliver improved awareness to air traffic controllers. At higher levels of implementation, the system aims to deliver safety nets to prevent imminent or actual hazardous situations from developing into major incidents or even accidents. The A-SMGCS system also includes conflict detection and resolution, planning and guidance information for pilots, as well as controllers, and detecting and indicating the position of potential hazards.
