A '''precision approach path indicator''' ('''PAPI''') is a system of [[Electric light|lights]] on the side of an airport [[runway]] threshold that provides visual [[descent (aircraft)|descent]] guidance information during [[final approach]]. It is generally located on the left-hand side of the runway approximately {{convert|300|m|ft}} beyond the landing threshold of the runway.
