Helicopter Approach Path Indicator HAPI System

     Overview:

The Helicopter Approach Path Indicator HAPI System allows the pilot to have the necessary visual information to place the helicopter on the ideal approach slope and can be used by day or night. 

The HAPI system can be used by all helicopter as soon as it is set up since it does not require any airborne instrumentation. In compliance with ICAO requirements the Helicopter Approach Path Indicator HAPI must be located adjacent to the nominal aiming point and aligned in azimuth with the preferred approach direction. 

The angle of elevation setting of HAPI must be such that during approach the pilot of the helicopter observing the upper boundary of the “Below Slope” sector (Fix Red) clear all objects in the approach area by a safe margin. 

The Helicopter Approach Path Indicator HAPI System which emit in elevation four distinct types of light : 

1. Flashing Green Light = Helicopter above the optimal approach slope optimum (too high).

2. Fix Green Light = Helicopter on the slope.

3. Fix Red Light = Helicopter slightly below the optimal slope (slightly too low).

4. Flashing Red Light = Helicopter below the optimal slope (too low).

     Compliance:

1. ICAO Annex 14 Volume II Heliports 5.3.

2. FAA  AC 150/5390-2A 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.

     Applications:

The Helicopter Approach Path Indicator HAPI System is used to glide slope on final approach to the helipad, it needs to use with other helipad light. Offshore or Onshore heliport both can use.
