airport helipad PAPI LIGHT

CDT PAPI LIGHTING / LAMPU KESELAMATAN

The PAPI system allows the pilot to have the necessary visual information to place the aircraft on the ideal approach slope and can be used by day and night.

The PAPI system consists of four-light units, which locate at the side of the runway adjacent to the origin of the glide path. The nominal glide slop angle is midway between the angular settings of the central pair of the four units.

If the aircraft approach is too high, an increased number of white light indicators will be seen. If the aircraft approach is too low, the pilot will see an increased number of red light indicators.
