HAPI is a modified PAPI system for use as visual slope guidance on heliports.
One HAPI system is for one helicopter approach path.
It is installed on the side opposite the approach, facing across the landing area.
Each HAPI system consists of two (2) HAPI units
Use Instruction:
The PAPI system is used to guide aircraft to approach the runway at an appropriate altitude.
The upper half of PAPI's beam is yellow, with green in the middle and red in the lower half. In
the visual range, different elevation lights in PAPI systems allow the aircraft to see different
colors at different altitudes. The pilot can judge and adjust the height of the plane by seeing
the color of the beam, making it at the right height. When the pilot saw the yellow ray means
to fly too high; when the pilot saw green said height at the right moment; when the pilot saw
the red light said flying too low, could hit obstacles.

A single lamp unit consists of a lamp body and three stents. The lamp body is composed
mainly of top cover, front glass panel, box body, lens, color filter, light bulb and bracket, and
the lamp is always provided with optical element positioning and protection. The bracket
assembly consists of flanges, easy folds, long poles, screws, nuts and gaskets, which are used
to support the lamp body and control the height and elevation of the lamp body.
