Airport PAPI System (Precision approach path indicator) & Heliport CHAPI System (Chase Helicopter Approach Path Indicator)

Airport PAPI System (Precision approach path indicator) & Heliport CHAPI System (Chase Helicopter Approach Path Indicator)

Standard

1.Annex 14 to the Convention on International Civil Aviation – Aerodromes 

2.AC-137-CA-2015-07 Precision approach path indicator

A precision approach path indicator (PAPI) is a visual aid that provides guidance information to help a pilot acquire and maintain
the correct approach (in the vertical plane) to an airport or an aerodrome.

Key Feature

1.Straight red-white boundary, red-white transition zone<3 arc minute, in compliance with ICAO Annex 14;

2. High precision, stable and reliable structure, easy to operate and maintain; 3. Electrical apparatus control system, PAPI system shut down if there is abnormality; 4. Internal electric inclinometer can reach a resolution value of 0.01° and Show the elevation Angle of the lamp 5. Able to store Angle data, elevation Angle over threshold shutdown system. 6. Closed optical system refrains foreign objects from entering on routine maintenance

Signals

If the beams of the PAPI system aim at the near slope in accordance with the prescribed Angle, Pilots see different colors at different heights. a) If the height is right, two lamps that are close to the runway are red, and the two lamps that are farther from the runway are white. b) If the height is high, you can see that the nearest light to the runway is red, and the three luminaries furthest from the runway are white. If the height is too high, all the lamps are white; c) If the height is low, you can see that the three lights closest to the runway are red, and the light from the farthest from the runway is white. When it is Far below to the approaching slope, all lights are red. APAPI system: a) If the height is right, the lamp that are close to the runway is red, and the lamp that are farther from the runway is white. b) If the height is high, you can see two lamps are white. c) If the height is low, you can see two lamps are red.
