Precision approach path indicator

Product description

PAPI lights are generally set on the left side of the runway (for approaching pilots), but can be set on the right side of the runway when it is physically impracticable to do so.

The PAPI system shall be constructed and arranged in such a manner that a pilot making an approach will:

a) when on or close to the approach slope, see the two units nearest the runway as red and the two units farthest from the runway as white;

b) when above the approach slope, see the one unit nearest the runway as red and the three units farthest from the runway as white; and when further above the approach slope, see all the units as white; and

c) when below the approach slope, see the three units nearest the runway as red and the unit farthest from the runway as white; and when further below the approach slope, see all the units as red.

Features

If the elevation angle exceeds the threshold, the system will be shut down. Each light comes with an electronic angle chip and display the elevation angle in real-time on LED digital tube, with an accuracy of 0.01°(0.6 cent).

Can store angle data.

You can set the "operation mode" and "calibration flight mode" separately, making debugging more convenient.

You can view the usage time data of each light source bulb at any time, count and record the operating status of the system.

The box contains calibration bubbles, which visually indicate the angle status after the "calibration flight" is completed.

Accurate self positioning design of light bulbs and filters, eliminating the need for recalibration of optical components, making replacement more convenient.

Small size, strong overall wind resistance, able to withstand wind speed of 161km/h.
