Airfield Lighting Control Panel (FAA L-821) 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
Airfield Lighting Control Panel (FAA L-821)
by Flight Light Inc.
Compact FAA L-821 airfield lighting control panel integrating relays, switches, and human interface in a single UL-listed cabinet, available as a conventional Type I or PLC touch-screen Type III system.
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.
