Heliport Approach Path Indicator AO-HP-CHAPI

The Heliport Approach Path Indicator (HAPI) is a vital tool used in aviation to assist helicopter pilots during the approach phase of landing. It provides visual guidance regarding the proper approach angle to a heliport or landing zone, enhancing safety and precision in helicopter operations.

HAPI typically consists of a series of lights arranged in a specific configuration alongside the approach path. These lights emit different colors, such as red and white, indicating whether the approaching aircraft is too high, too low, or on the correct glide path.

By interpreting the color combinations displayed by the HAPI lights, pilots can make real-time adjustments to their approach angle to ensure a safe and controlled landing. This guidance is especially crucial during adverse weather conditions or low visibility, where visual cues become limited.

One of the key benefits of HAPI is its ability to provide accurate and consistent guidance to pilots regardless of environmental factors. This enhances situational awareness and reduces the risk of controlled flight into terrain (CFIT) accidents, which are a significant concern in helicopter operations.

Furthermore, HAPI is designed to be easy to install and maintain, making it a cost-effective solution for heliport operators and aviation authorities. Its intuitive design and effectiveness in improving landing safety make it a standard feature in many heliports and landing zones worldwide.

In conclusion, Heliport Approach Path Indicator (HAPI) plays a crucial role in enhancing the safety and efficiency of helicopter landings. By providing clear visual guidance to pilots during the approach phase, HAPI helps mitigate risks and ensures precise and safe landings in various operational conditions.

     Overview:

The mode AO-HP-CHAPI Heliport Approach Path Indicator AO-HP-CHAPI CHAPI light, its full name is Heliport Approach Path Indicators, CHAPI is its short name. The "C"’ in CHAPI stands for ‘Cramp’, the name of person who invented the system 40 years ago. so until now, we still use CHAPI stands for HAPI lights. Our LED CHAPI uses LED technology to provide the pilot with safe and accurate glide slope on final approach to the helipad. A set of two LED CHAPI Light Housing Assemblies (LHAs) are seen by the pilot in combinations of white, green and red to indicate a path that is too high, too low or within the 6° ±0°15′ glide slope. Angle deviations that are too high show one or two white lights, and those that are too low show one or two red lights. HAPI light Visual Indication as follows, one helipad needs 2 pcs HAPI lights:

     Compliance:

1. ICAO Annex 14 Volume II Heliports 5.3.

2. FAA  AC 150/5390-2B Heliport Design Guide

     Features:

1. Adopt super bright brand LED, high intensity with a lower energy consumption.

2. Input voltage available in DC(12-48V DC) or AC(100-265V AC 50-60Hz).

3. Clear polycarbonate lens for converging light and also provides corrosion resistance and UV protection.

4. Efficient photometric design provides excellent light distribution, make sure meet ICAO and FAA demand.

5. Housing material is stainless steel which has strong corrosion resistance, Shock and Vibrations protection.

6. UV protection Powder coated bright yellow color base make better visibility.

7. Fragile coupling reduce the secondary damage to helicopters effectively.

     Dimension & Installation:

The recommended location for installing the CHAPI Light is shown in above picture.  The size of the helipad is dependent on your location and the maximum rotor diameter.  The 3.28 foot dimension listed is important to help locate the CHAPI nearest the helipad and assist helicopter pilots. After the elevation and exact physical location of the light boxes, then mount the light boxes on the pads. 

     Applications:

Heliport Approach Path Indicator AO-HP-CHAPI is sued to glide slope on final approach to the helipad, it needs to use with other helipad light. Normally a helipad needs 2 pcs CHAPI light.
