Heliport Approach Path Indicator for Heliport Lighting

The Heliport Approach Path Indicator (HAPI) is a crucial component of heliport lighting systems that provides visual guidance to helicopter pilots during approach and landing. It consists of a row of lights installed along the final approach path to the heliport. The HAPI system emits a series of lights that indicate to pilots whether they are too high, too low, or on the correct glide path for a safe landing.

Typically, the HAPI system consists of a combination of red, white and green lights. When the lights appear white, it indicates that the helicopter is on the correct glide path. If the lights appear red, it indicates that the helicopter is too low and needs to adjust its altitude. Conversely, if the lights appear white above red, it means the helicopter is too high and needs to descend for a proper approach.

The HAPI system is especially useful during night operations or in low visibility conditions when visual references are limited. It enhances safety by providing pilots with clear and precise guidance during the critical phases of approach and landing. The Heliport Approach Path Indicator is an essential tool in heliport lighting systems, ensuring the safe and efficient operation of helicopter traffic.

     Overview:

The mode AO-HP-CHAPI HAPI 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:

AO-HP-CHAPI Heliport Approach Path Indicator 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 HAPI light.
