The HA SFLS Approach Lighting System is designed to provide enhanced visual guidance to pilots during approach, significantly improving safety and accuracy. At the core of its functionality are sequenced flashing lights that create a clear, rhythmic visual pattern along the approach line. This sequence guides pilots effectively, especially in challenging conditions such as low light or adverse weather, ensuring safer and more precise navigation to the landing zone.
The system comes equipped with a standard configuration of four sequenced flashing lights, strategically positioned to offer comprehensive illumination of the approach path. This setup ensures that pilots receive consistent visual cues as they align their approach, reducing the likelihood of errors. The lights themselves utilize high-power LEDs, delivering a strong light output exceeding 3,500 candelas, with a long service life rated at more than 75,000 hours, which translates to low maintenance requirements and reliable long-term performance.
Durability is a key aspect of the HA SFLS system. Its components are built to withstand harsh environmental conditions, including exposure to rain, wind, and extreme temperatures. The approach lights feature robust construction with steel cabinets finished in a gray RAL 7035 powder coating, providing excellent resistance against corrosion and wear. Each approach light measures Ø133 by 240 millimeters and weighs approximately 2.1 kilograms, while the controller unit measures 340 by 400 by 170 millimeters and weighs 15 kilograms, making the system manageable for installation and maintenance.
The controller unit operates on a power supply of 110-240 VAC and is equipped with secure cable glands—one M25 input and four M20 outputs—to ensure safe and efficient electrical connections. This combination of advanced lighting technology, sturdy construction, and thoughtful design ensures the HA SFLS Approach Lighting System maintains continuous, reliable operation. The system is compliant with international aviation safety standards, including ICAO Annex 14 Volume I for Aerodromes, ICAO Annex 14 Volume II for Heliports, and EASA ADR regulations, making it suitable for a wide range of airports and helipads seeking to enhance approach safety.
