Two white lights and two red lights mean you're on the established glide path on a PAPI. In some cases, the required length for an Approach Lighting System cannot be fully provided in accordance to ICAO or EASA requirements: due to topographical. The visual glide path of the PAPI typically provides safe obstruction clearance within plus or minus 10 degrees of the extended runway centerline and to 3.4 NM from the runway threshold. These lights are visible from about 5 miles during the day and up to 20 miles at night. Not only does it have the approach light system, it also tells you the type of runway lighting. The Solar Series ODALs (Omni-Directional Approach Lights) are used to identify the approach end and centerline of the runway. The second spot you can look is the airport diagram. In this case, KTKI has a MALSR on Runway 18. PAPIs use lights similar to the VASI, but are installed in a single row of either two or four light units. The top of the chart shows the type of approach lighting system for your approach runway. The Precision Approach Path Indicator (PAPI) is another very common visual glide path indicator light. Although normal glide path angles are 3 degrees, VASI lights at some airports may be as high as 4.5 degrees to give proper obstacle clearance. If you see two red lights over two white lights, you're on glide path. The visual glide path of the VASI provides safe obstruction clearance within plus or minus 10 degrees of the extended runway centerline and to 4 NM from the runway threshold. These lights are visible from 3-5 miles during the day and up to 20 miles or more at night. The Visual Approach Slope Indicator (VASI) is a system of lights arranged to provide visual descent guidance information during the approach to a runway for VFR and IFR pilots.
