The '''Precision Approach Path Indicator (PAPI)''' is a light system positioned beside the [[runway]] that consists of two, three, or four boxes of lights that provide a visual indication of a [[fixed-wing aircraft]]'s position on the [[glidepath]] for the associated runway. The [[Federal Aviation Administration|FAA]] standard for the PAPI is the same as the [[ICAO]]'s standard [[VASI|Visual Approach Slope Indicator]].
