SGS is a system that provides guidance to the A/c operating on the aerodrome area. It is an extension of the HUD system, which utilizes the pre- set guidance for the operations on the Airport area.
It significantly reduces the risk of Runway and Taxiway incursions.
It can also provide the full guidance from the runway to the ramp via course guidance pointers guiding the A/c to turn and follow the indications. When being cleared by the ATC through its clearance made through data link communications, without making verbal communications, since the clearance can be sent through the data link communications and can be displayed on the A/c display unit. It also eliminates the tiresome process of communicating in a high density airport as well as cut the requirements of reading back the instructions verbally. The system is not active as of now, but is expected to be in operation soon.
