LED Taxiway Edge Light (FAA L-861T) vs Advanced Visual Docking Guidance System / A-VDGS (RLG Docking Systems, distributed by Vardhman Airport Solutions)
Spec comparison for two products on Aviation Souk. Both compete in Runway Lighting & Airfield Electrical.
Runway Lighting & Airfield Electrical
LED Taxiway Edge Light (FAA L-861T)
by Flight Light Inc.
Die-cast aluminium LED taxiway edge light with blue glass lens, ETL-certified to FAA L-861T, designed for direct installation on existing L-867 base plates across 14–30 inch mounting heights.
Runway Lighting & Airfield Electrical
Advanced Visual Docking Guidance System / A-VDGS (RLG Docking Systems, distributed by Vardhman Airport Solutions)
by Vardhman Airport Solutions
A 3D laser-scanning docking guidance system from RLG Docking Systems (Taiwan) that tracks incoming aircraft nose position in real time and displays stopping and azimuth guidance to the flight deck — eliminating the weight and height variables that defeat simpler optical systems.
