HAPI (PLASI) Pulse Light Approach Slope Indicator  

Devore Aviation's Pulse Light Approach Slope Indicator (PLASI) systems are a visual approach aid for use in visual flight conditions. The system provides the pilot with a stabilized approach by means of a single light source from a position adjacent to the intended touchdown point of a runway or helipad.  To date, over 500 units have been installed worldwide.  ICAO HAPI PLASI system is fully ICAO compliant per Annex 14.

HAPI (PLASI) Pulse Light Approach Slope Indicator  

Pulse Light Approach Slope Indicator (PLASI) systems are a visual approach aid for use in visual flight conditions.

Operational Capabilities

  • The PLASI system has an effective visual range of 5 nm during the day and up to 20 nm at night.  
  • A pilot who is flying the approach on glide path will see a steady white light.  If he should above the glide path, he will see a pulsing white light.
  • Alternatively, if the pilot begins to descend below glide path, he will first see a steady red light that turns into a flashing red light the lower he goes.

 

Installation and Set Up

  • PLASI systems are self-contained units, requiring no extra equipment in the aircraft to utilize.
  • The HAPI-PLASI system for heliports comes mounted on a rotating turntable, thus providing the approaching helicopter pilot the ability to position the unit (via a ground or aircraft controlled radio) to capitalize on wind direction and/or minimize noise impact. 
  • PLASI units for airports, heliports, temporary and tactical (infrared) operations are FAA (PLASI 2000 and HELI-PLASI) and ICAO (HAPI-PLASI) approved and are readily transportable and easily installed.

 

Key Benefits of PLASI Approach Systems

  • Portable, compact and easy to install
  • Low annual maintenance cost (warranty)
  • Can provide multiple approach capability
  • Improves helicopter landing operations and safety
  • Ideal for remote, emergency or temporary situations
  • Inexpensive solution for visual approach requirements
