A-VDGS (Advanced Visual Docking Guidance System) is an automated system used at airport gates to assist pilots in precisely aligning and stopping an aircraft during the final phase of taxiing to the parking stand. It replaces traditional marshallers or basic docking aids by using sensors, cameras, and visual displays to provide real-time, highly accurate guidance on position, speed, and stopping point. The system detects the approaching aircraft, identifies its type, and guides the pilot using visual indicators—typically LED lights—to ensure safe, efficient, and optimized docking, improving turnaround time and reducing the risk of collisions or ground handling errors.
