The Elevated Runway Guard Light (AV-ERGL) is a solar-powered, unidirectional LED fixture designed to provide a highly visible warning to pilots and vehicles approaching an active runway. This yellow, alternately flashing light delivers 45 to 50 flashes per minute and is typically installed in pairs on either side of the taxiway holding position to mark runways and taxiway intersections effectively. The AV-ERGL offers 24-hour unidirectional marking without the need for trenching, cabling, or connection to mains power, allowing for quick installation and easy relocation.
Powered by energy-efficient LEDs with an average lifespan exceeding 100,000 hours, the AV-ERGL significantly reduces maintenance and relamping costs. The solar module integrated into the system can be angled to optimize sunlight collection, charging the sealed lead acid battery efficiently while promoting clean, renewable energy use and minimizing environmental impact. This design results in considerable savings in both power consumption and installation expenses. The light beam elevation is adjustable in precise one-degree increments with a positive locking mechanism, enabling tailored illumination based on specific site requirements.
Constructed with a high-strength powder-coated frame and aluminum housing, the AV-ERGL features stainless steel hardware for enhanced durability and corrosion resistance. It is equipped with a 2-inch FAA-compliant frangible coupling and tether with positive lock canting, engineered to withstand jet blast forces of up to 300 miles per hour, ensuring the light remains operational in harsh airfield environments. The baseplate uses a six-hole bolt pattern for secure mounting, and the power supply incorporates fuse bolts certified to FAA AC 150/5220-23 standards.
This runway guard light is designed to increase visibility at hold positions during adverse weather conditions and serves as a critical traffic signal for airport service roads. Its configurable intensity settings, typically two-step adjustments for dusk and dawn, allow it to adapt to varying operational needs. The AV-ERGL complies fully with FAA AC 150/5345-46 (current edition) for L-804 applications and adheres to ICAO Annex 14, Volume 1, 2013, specifically paragraph 5.3.23 and Appendix 2 Figures A2-24 and A2-25, ensuring it meets all relevant international and federal aviation standards.
Overall, the AV-ERGL is a low-maintenance, environmentally responsible solution offering robust construction, efficient solar power utilization, and superior visibility for runway safety enhancement.
