Approach light AL-119-28-WH-RE

PAPIlandingposition

Precision Approach Path Indicator – PAPI Designed and built with simplicity and ease of maintenance in mind LED technology Lightweight, low-energy, and environment-friendly lighting fitting Extensive use of aluminum alloys reduces fitting weight and eases handling in the field Certified/Compliant According to Standards: International Civil Aviation Organization, Aerodromes, Annex 14, Volume 1, Seventh Edition, dated July 2016 Photometric – (ICAO) Figure A2-23 Light intensity distribution of PAPI and APAPI Chromaticity – Section 5.3.5.30 Description Precision Approach Path Indicator – PAPI These units can be used to create the PAPI or APAPI systems used on Heliports or Airports. The purpose is to signal the pilots if they are on the correct landing angle. Depending on the approach angle combination of white and red lights will be seen. More reds mean the angle is too low, more white means it is too high. Housing powder-coated aluminum, RAL 1004 (aviation yellow) Anti-glare visor powder-coated aluminum, RAL 1004 (gloss black) Diffuser hardened front glass for sandblasting protection Cable gland nickel-plated brass Fastening system powder-coated aluminum, RAL 1004 (aviation yellow) In the unit, it is integrated an electronic clinometer. The calibration is made in the factory so the user has just to install the PAPI on the desired angle then push the user calibration button. From this position, if the reading is changed with half-degree the light will automatically be turned OFF and one relay will have an open circuit to signal the failure. Electrical Characteristics Precision Approach Path Indicator can be made in more powering input voltages
