Advanced Visual Docking Guidance System / A-VDGS (RLG Docking Systems, distributed by Vardhman Airport Solutions) vs Constant Current Regulator (CCR) & Airfield Lighting Control & Monitoring System / ALCMS (distributed/integrated by Vardhman Airport Solutions)
Spec comparison for two products on Aviation Souk. Both compete in Runway Lighting & Airfield Electrical.
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.
An integrated microprocessor-controlled series-circuit power supply and airport-wide lighting supervisory system — the CCR and ALCMS working together to maintain constant lamp current across all five brightness steps while giving ATC complete monitoring and switching authority over every airfield lighting circuit.
