Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a device for checking a sensor of an aircraft landing system,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sensor checking device set, and more particularly, to a sensor checking device set of an aircraft landing system.

Military airplanes, such as advanced trainer aircraft, are inspected by various inspection devices to check hundreds of thousands of parts. The inspection method is different for each part. If necessary, the process of disassembly and assembly may be accompanied, and the inspection may be simply performed without disassembly and assembly.

However, there are many cases in which a simple inspection is also carried out through a complicated inspection procedure through the inspection device of the hangar.

However, the landing gear of the aircraft's landing gear is exposed to the outside and can be easily inspected without disassembling and assembling through exposed parts.

Specifically, the status check is performed by checking on / off of various micro switches provided at the landing gear landing gear.

However, conventionally, in order to carry out such inspection, the aircraft had to be moved to a maintenance hangar for inspection.

However, the inspection that does not involve such disassembly / assembly should be carried out easily without moving to the maintenance hangar, and it is necessary to operate it immediately and save the procedure, time or effort.
