The AV-ERGL (Elevated Runway Guard Light) is a unidirectional, alternately flashing LED fixture designed to alert pilots and vehicle operators that they are approaching an active runway or a taxiway holding position. Providing continuous 24-hour unidirectional marking, the AV-ERGL emits 45 to 50 alternating yellow flashes per minute, serving as a critical visual warning at runway intersections to enhance situational awareness and operational safety. Typically installed in pairs on either side of the taxiway holding position, these lights play an essential role in preventing runway incursions.
One of the key advantages of the AV-ERGL is its ease of installation and flexibility. The solar-powered version requires no trenching, cabling, or connection to mains power, allowing for rapid setup and easy relocation as needed. This makes it highly adaptable for both permanent installations and temporary or evolving airfield layouts. Its energy-efficient LED technology boasts an impressive lifespan exceeding 100,000 hours, significantly reducing maintenance needs and operational costs over the long term.
The AV-ERGL is engineered for durability and reliability in demanding aviation environments. The light beam elevation is fully adjustable in precise one-degree increments, secured by a positive locking mechanism to ensure optimal beam positioning and consistent performance. The fixture is constructed from a high-strength, powder-coated aluminum frame with stainless steel hardware, offering corrosion resistance and robust protection against harsh weather and environmental conditions. Its 2-inch frangible coupling and tether include a positive lock canting feature designed to absorb impact safely. Additionally, the AV-ERGL can withstand jet blast forces up to 300 miles per hour, making it suitable for placement in high-stress airport areas.
Beyond its primary function as a runway guard light, the AV-ERGL finds application in enhancing visibility during severe weather conditions and as traffic signals for airport service roads. Its compliance with major international standards affirms its quality and suitability for global use. The light meets FAA AC 150/5345-46 (current edition) specifications for L-804 applications and adheres to ICAO Annex 14, Volume 1 requirements, including specific paragraphs and appendices detailing elevated runway guard light performance. It also conforms to European CE standards EN61000-6-4:2012 and EN61000-6-2:2019, with manufacturing quality assured under ISO 9001:2015 certification.
The AV-ERGL is available in standard colors such as desert tan and yellow, with additional colors offered upon request to match airport-specific requirements or aesthetic preferences. It delivers peak intensity levels of approximately 300 candelas during daytime operation and 30 candelas at night, ensuring high visibility without causing glare. Some configurations provide enhanced peak intensities of up to 3,000 candelas in daylight and 300 candelas during nighttime, accommodating various airfield lighting needs. The unit operates on a 24-volt power supply and is protected by integrated circuit safeguards, guaranteeing safe and stable electrical performance. The operating temperature range spans from -40°C to 55°C, enabling reliable function in extreme climatic conditions.
Overall, the AV-ERGL combines energy-efficient LED technology, rugged construction, precise adjustability, and international compliance to provide airports with an effective and maintenance-friendly elevated runway guard light solution that enhances safety at critical runway and taxiway intersections.
