Cramp's Helicopter Approach Path Indicator heliport Approach Path Indicator CHAPI light for heliport lighting

Cramp's Helicopter Approach Path Indicator (HAPI) is a vital safety system designed to guide helicopter pilots during their final approach and landing phases. The system uses a series of color-coded lights, typically green and red, to visually indicate whether the helicopter is on the correct glide slope. Green lights signal that the helicopter is on the optimal path, while red lights warn when the helicopter is too high or too low, enabling pilots to adjust their descent.

Cramp's HAPI system ensures safe landings, particularly in low-visibility or nighttime conditions, by providing clear and real-time feedback on the aircraft's position relative to the desired approach slope. Built with durable, weather-resistant materials and energy-efficient LED technology, it offers low maintenance and long-lasting reliability. This system is widely used in various heliports, hospital rooftops, and offshore platforms, complying with international standards such as ICAO and FAA. It plays a crucial role in enhancing the safety of helicopter operations in diverse environments.

     Overview:

The CHAPI Light System, specifically the AO-HP-CHAPI, stands for Heliport Approach Path Indicators, with "CHAPI" being the abbreviation. The "C" in CHAPI honors 'Cramp,' the inventor of the system over 40 years ago, and to this day, we continue to use CHAPI to refer to HAPI lights. Our LED CHAPI system uses advanced LED technology to guide pilots safely and accurately along the correct glide slope during their final approach to the helipad.

The system consists of two LED CHAPI Light Housing Assemblies (LHAs), visible to the pilot, which display a combination of white, green, and red lights to indicate whether the helicopter is above, below, or on the ideal 6° ±0°15′ glide path. Excessive angle deviations are shown by one or two white lights for too high an approach, and one or two red lights for too low an approach. Each helipad requires two HAPI lights to ensure full visibility and safe approach guidance.

Cramp's Helicopter Approach Path Indicator (CHAPI) is a crucial safety system for guiding helicopter pilots during their final approach to a helipad. Using a set of LED lights, it provides clear visual feedback on whether the helicopter is above, below, or on the correct glide slope. Green lights indicate an optimal approach, while red and white lights signal deviations. CHAPI ensures safe landings, especially in low-visibility conditions, and is widely used in heliports, hospital rooftops, and offshore platforms.
