What Does PAPI Stand For?

PAPI stands for Precision Approach Path Indicator

PAPI, or Precision Approach Path Indicator, is an optical ground-based system designed to provide visual guidance to pilots during the approach and landing phases of flight. It consists of a series of lights arranged in a specific configuration that indicate whether an aircraft is on the correct glide path to the runway. By displaying combinations of red and white lights, PAPI helps pilots maintain the appropriate angle of descent, enhancing safety and improving landing accuracy in varying visibility conditions.
