Description

Technical Field

[0001] This application relates to the field of aircraft landing light adjustment, and in particular to a method for adjusting the spotlight of an aircraft landing light. Background Technology

[0002] Aircraft landing lights are important external lighting equipment for aircraft, providing sufficient light for safe nighttime landings. When landing at night, the landing lights are required to illuminate a short distance of the runway in front of the aircraft, ensuring sufficient and clear illumination on the runway so that the pilot can accurately judge the landing path and runway conditions.

[0003] Aircraft typically have 3-4 landing lights, one installed on the left and right bulges at the front of the fuselage, and another near the front emergency exit. During ground testing, the three landing lights are required to converge at a specific distance in front of the nose, such as 60 ± 3 meters, with the beam covering a certain area, such as ± 12 meters. To prevent light interference, operators generally conduct light testing at night, ensuring unobstructed views in front of the nose and within a ± 60° radius to the left and right. Operators visually observe the light convergence point. A measuring tape is then used to measure the distance from the light convergence point to the front of the nose, as well as the range of the lights. The unclear edges of the light convergence line pose significant challenges to measurement. Measurements taken by different personnel vary considerably, making quantification, recording, and adjustment difficult. Summary of the Invention
