Airport PAPI Lighting Systems

Precision Approach Path Indicator (PAPI)

PAPI (Precision Approach Path Indicator) lighting systems are visual aids installed at airports to help pilots make a safe landing. The system consists of two or four white lights and two or four red lights, arranged vertically. The lights are positioned on the side of the runway and provide a visual indication of the aircraft's height and alignment with the runway during approach. If the white lights are visible, it indicates that the aircraft is at the correct height, while if the red lights become visible, it indicates that the aircraft is too low and needs to adjust its height. PAPI lighting systems are critical components of modern aviation infrastructure and are widely used at airports around the world.

Airport Approach & Threshold Lighting - Precision Approach Path Indicator (PAPI)

The Precision Approach Path Indicator (PAPI) is a visual guidance lighting system that provides pilots with essential information regarding the correct approach to an airport. It is typically located beside the runway and helps pilots maintain the correct glide path during landing.

The primary purpose of PAPI is to assist pilots in achieving a safe and accurate descent angle as they approach the runway. By utilizing a series of lights, usually consisting of four light units, PAPI provides visual cues that indicate whether the aircraft is too high or too low in relation to the desired glide path.

Each light unit in the PAPI system emits a combination of red and white lights. When an aircraft is on the correct glide path, two white lights and two red lights are visible to the pilot. This indicates that they are approaching at an optimal angle for landing.

If an aircraft is too high, more red lights will be visible than white lights. Conversely, if it is too low, more white lights will be visible than red lights. This allows pilots to make immediate adjustments to their descent angle and ensure a safe landing.

PAPI serves as a valuable tool for both experienced and novice pilots by providing clear visual guidance during critical phases of flight. Its presence alongside runways enhances safety by minimizing potential errors in altitude during landings, ultimately contributing to smoother operations at airports worldwide.
