Precision Approach Path Indicator (PAPI Lights, APAPI Lighting)

Precision Approach Path Indicator (PAPI Lights, APAPI Lighting)

The Avlite LED PAPI is a highly efficient Precision Approach Path Indicator that uses LEDs as a light-source to provide low maintenance, low power consumption and high levels of reliability. The unit operates from 24VDC for energy efficiency and increased safety, and can be
supplied with optional solar power supplies, AC input or traditional CCR.

Patented LED Optics
Innovative optics achieve the industry’s lowest power consumption, uniform intensity, and sharpest red/white transition for critically accurate approach slope information to the pilot.

Field Proven Design
The Avlite LED PAPI was developed by Laser Guidance Inc, a United States designer and manufacturer of high precision aviation lighting products. Now in its 2nd generation, over 100 systems have been deployed globally in regions including the Americas, Europe, Middle East, Asia and Africa.

Permanent or Portable Operations
Available with permanent frangible or temporary mounting legs, the PAPI is designed to support various usage conditions.
Designed for Commercial or Military Applications The Avlite LED PAPI is one of the only PAPIs on the market capable of supporting
visual and infrared operational states within the same optic. Switchable by ground operators, the visual PAPI allows pilots to identify approach slope information using traditional means of WHITE/RED light combinations. Infrared mode allows pilots using night vision equipment to approach on the same reference points using a combination of steady and occulting outputs.
