Precision Approach Path Indicator (PAPI)

Description

Characteristics:

• Luminance, chromaticity align to requirements of CAAC Technical Specification of Precision Approach Path Indicator (AC-137-CA-2015-07) and ICAOAnnex 14. Clear and straight transition line between red and white signals.
• Intelligentelectrical control system. In case of abnormal defined in CAAC, FAA and ICAO, PAPI system automatically turn off the lights and lead to CCR undervoltage.
• Each lighting fixture equipped with electronic angle chip, andLED digital tube instant  Accuracy up to +0.01°. Angle data can be stored. The system will turn off if elevation exceeds threshold.
• Control system and heat sources effectively isolated, to avoid failures due to overheating.
• Two separated mode, “Operation”mode and “Calibration” mode, more convenient for usage.
• Three landing leg height adjustment mechanisms makeson-site installation and calibration convenient and accurate
• Precise self-positioning design, re-calibration is unnecessary when replacing bulbs and filters.
• Main body is madeof aluminum alloy with special surface treatment. And the fasteners are made of high-quality stainless steel. Lightweight, sturdy and high anti-corrosion
• Small size, strong wind resistanceup to 320KM/HPrecision machined frangible parts align to the requirements of CAAC and FAA. Performance stable and reliable.
