Precision Approach Path Indicator (PAPI) Lights

ICAO, FAA and STANAG Compliant APAPI/PAPI System
Categories: , , Tag:

Abbreviated PAPI (APAPI) and Precision Approach Path Indicator (PAPI) lights provide pilots with a safe and accurate glide slope on the final approach to the runway. A PAPI aviation light system uses a row of light housing assemblies (LHAs) placed perpendicular to the airport’s runway approach path. Pilots can easily determine if their approach is too high, too low or correctly on-slope through combinations of red and white lights. Aviation PAPI light systems are available in 3 basic models with multiple configuration options to meet ICAO, FAA and STANAG requirements.



  • Permanent runways
  • Temporary runways
  • Emergency runways
  • Military & NVG operations


Easy Installation

PAPI lights work equally well in permanent or temporary locations. Permanent mounting is easy with standard frangible mounting. Temporary deployment is fast with retractable legs and a lightweight, compact form factor.


Advanced Optics

Flash’s PAPI light system and the abbreviated PAPI (APAPI) use patented, LED-based optics to achieve the lowest power consumption, highest intensity and sharpest white/red transition. Aviation PAPIs exceed ICAO, FAA and STANAG requirements to provide a clear approach path to the aviator.


Power Supply Versatility

The low power consumption of the PAPI light system makes it mate well with several available power supplies:

  • Solar kit
  • Generator kit
  • Battery kit
  • AC only



Optional wireless control provides remote operation of the PAPI unit using either 900 MHz or 2.4 GHz communication. There is also 3 and 5-step wired control and local control available.
