Description

technical field [0001] The invention relates to an airport PAPI lamp test tool, in particular to a precision approach channel indicator lamp indication angle test system and a test method. Background technique [0002] The precision approach course indicator is commonly known as the slope light (or PAPI light), which is a kind of light that gives the pilot the approach glide angle. Due to the stability of the light, it can provide the pilot with reliable information within the visual range. The descending angle signal prompts the pilot to correct the landing angle of the aircraft before the final landing. The intuitiveness of the slope light can prevent the wrong indication of instrument landing. For the pilot, the indication angle of the slope light is related to the safety of the aircraft. Currently, the correction to the slope light indicates the angle. Airplanes are generally used for school flights, and the results of school flights are reliable, but the cost of school...

AI Technical Summary

Problems solved by technology

Airplanes are generally used for school flights, and the results of school flights are reliable, but the cost of school flights is quite expensive. For airports, it is not a small expense to conduct them every six months or a year, and the airport maintenance manual It is required to test once a week. For the airport, it is impossible to realize it through flight calibration, and the airport personnel do not have corresponding detection means to correct the slope light. The error of the slope light cannot be eliminated in time, which will have a certain impact on the landing of the aircraft. even dangerous

A Chinese utility model patent (patent number: 00202332.6, announcement date: June 6, 2001) describes a gradient light calibrator, which mainly consists of a front pole base, a rear pole base, and a front and rear pole base. It is an automatic calibration device composed of a liquid-filled connector connected for level indication, mainly consisting of a front pole mounted on the front pole base, a rear pole mounted on the rear pole base, a display, and a color monitor mounted on the rear pole base. The display calibration device composed of the device uses the right triangle principle to test the angle of the slope light. After changing the height of the benchmark, the color monitor moves accordingly, and displays the light image of the slope light through the display. The distance from the benchmark can be used to obtain the tangent value of the angle of the slope light, thereby obtaining the angle of the slope light. This patent can be used for convenient measurement and adjustment of the slope light, saving the cost of flight calibration. Its measurement accuracy can reach ±0.5′, but its measurement The accuracy is low, the measurement method is more complicated, and the instrument arrangement and adjustment are very inconvenient when measuring
