Visual Docking Guidance Terminal System (VDGS)
Visual Docking Guidance Systems (VDGS) greatly improve safety at the gate. A standard VDGS is designed for ramp positioning only and utilizes both human and mechanical elements to guide pilots to bring the airplane nose-in and stops the aircraft in a precise position where boarding bridges and fuel pits are easily accessible.
The new generation of docking guidance equipment is a fully automated, active system that ICAO classifies as an Advanced Visual Docking Guidance System (A-VDGS). UBS Airport Systems’ advanced visual docking guidance system benefits the airport, pilots and aircraft crews by saving time and greatly reducing the risk of damage to the plane during marshaling onto the bay. ICAO ANNEX 14, Volume 1, Paragraph 5.3.25 defines advanced visual docking guidance as those systems that provide pilots with active guidance information in at least three stages: acquisition of the aircraft by the system, the azimuth alignment of the aircraft and the stopping position information. In addition, an A-VDGS must provide accurate guidance to pilots in both seats.
