Helicopter Approach Path Indicator (HAPI)

ICAO, FAA and STANAG Compliant HAPI system
Categories: , , Tag:

HAPI (helicopter approach path indicator) systems provide pilots with a safe and accurate glide slope on final approach. Pilots can easily determine if their approach is too high, too low or correctly on-slope through combinations of red and green lights. Flash’s LED HAPI light is available in 2 basic models with multiple configuration options to meet ICAO, FAA and STANAG requirements.



  • Permanent helipads
  • Temporary helipads
  • Emergency helipads
  • Hospital helipads
  • Remote helipads
  • Military & NVG operations


Easy installation

The LED HAPI system works 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

The HAPI light uses patented, LED-based optics to achieve the lowest power consumption, highest intensity and sharpest green/red transition. It exceeds ICAO, FAA and STANAG helipad requirements to provide a clear approach path to the aviator.


Power supply versatility

The low power consumption of the HAPI makes it mate well with several available power supplies:

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



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



Deployed around the globe, from military to civilian airfields and from South East Asia to Northern Europe, the HAPI lighting system has proven it is robust.
