Types of Helipad Perimeter Lighting
White Perimeter Lights
White perimeter lights are the most commonly used type of helipad perimeter lighting. These lights outline the edges of the helipad, providing a clear visual boundary for pilots. They are typically positioned at regular intervals around the perimeter, ensuring consistent illumination and visibility from all angles. White perimeter lights are essential for helping pilots judge the size and shape of the landing zone accurately.
Green Threshold Lights
Green threshold lights are positioned at the entry points of the helipad, indicating the preferred landing direction. These lights guide pilots during the final approach, ensuring that they align correctly with the landing area. Green threshold lights are particularly useful in guiding pilots to the safest and most efficient approach path, reducing the risk of errors during landing.
Elevated and Inset Lights
Helipad perimeter lights can be either elevated or inset. Elevated lights are mounted above the surface and are more visible from a distance, making them suitable for areas with obstructions or uneven terrain. Inset lights, on the other hand, are embedded in the surface of the helipad, providing a flat, unobstructed area for helicopter operations. The choice between elevated and inset lights depends on the specific requirements and constraints of the helipad location.
LED Perimeter Lights
LED (Light Emitting Diode) technology has revolutionized helipad perimeter lighting. LED lights offer several advantages over traditional incandescent or halogen bulbs, including:
Energy Efficiency: LEDs consume significantly less power, reducing energy costs and environmental impact.
Longevity: LEDs have a longer lifespan, reducing the need for frequent replacements and lowering maintenance costs.
