Supply, Delivery, Installation, and Testing of Aeronautical Ground Lighting & Airfield Control Systems at Rajbiraj Airport

Overview

Mahavir Shree International Pvt. Ltd. supplied, delivered, installed, and tested an Aeronautical Ground Lighting System (AGLS) and an Airfield Lighting Control and Monitoring System (ALCMS) at Rajbiraj Airport for the Electromechanical Department of the Civil Aviation Authority of Nepal (CAAN), under reference SF-79-2658. The project replaced the airport's existing conventional AGL infrastructure, which had limited reliability, inadequate illumination, and no centralized control, with an LED-based lighting system integrated with a PLC-based ALCMS. The project ran approximately 1 year 2 months and 5 days, completing in December 2024.

Scope & Deliverables

• Airfield lighting: high-intensity runway edge lights (elevated and inset types), runway threshold and end lighting systems, taxiway and turning pad LED lighting systems, and Runway Threshold Identification Lights (RTIL).
• Apron and flood lighting: high mast LED flood lighting system for apron illumination, 16-meter high mast structures, and integration of obstruction lights and lightning protection systems.
• Power supply and control: Constant Current Regulators (CCR), Automatic Voltage Regulators (AVR) and UPS systems, a PLC-based ALCMS with HMI control interface, and integration with control tower systems for centralized operation.
• Cabling and infrastructure: AGL primary and secondary cables, optical fiber communication systems, ducts, manholes, and cable routing infrastructure, and complete earthing and lightning protection systems.
• Safety and navigation systems: runway signage and guidance systems, wind direction indicators and aeronautical beacons, and fire alarm systems, sirens, and signal light guns.
• Civil works: foundation construction for lighting and equipment systems, RCC chambers, mounting bases, and structural supports, and relocation and upgrading of existing systems including APAPI and floodlight masts.
• Pre-shipment inspection and testing, complete system testing and commissioning, supply of spare parts, and warranty support.

Outcome

The AGLS and PLC-based ALCMS were tested, commissioned, and handed over to CAAN's Electromechanical Department, enabling centralized control, real-time monitoring, and fault detection of runway, taxiway, and apron lighting from a single interface, with backup power provided through the installed CCR, AVR, and UPS systems. Training programs were delivered for airport technical staff on system operation. The work was carried out in accordance with ICAO regulations.
