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.
