Papi lights

Papi lights

What are the PAPI lights and what do they do? The lights are evenly spaced and the luminous flux is color-coded to provide a visual indication of the aircraft's approach position relative to the established glide path for the runway course. The properties of each light element are identical: each PAPI luminaire consists of a light source, a red filter and a lens.

Where are the PAPI lights located on the runway?

The PAPI is generally located on the left side of the lane, perpendicular to the lane's centerline. The distance between the blocks is 9 meters and the closest block is 15 meters from the edge of the runway. If necessary, PAPI can be installed on the right side of the track. Red lights are always on the side closest to the track.
