It used a system that flashes the light.

The structure is as follows. (1) A large number of aviation beacons, such as approach signs, were distributed and arranged around the runway of the airport, and each approach sign was made to flash asynchronously in a predetermined second cycle. .. However, according to the lighting system having such a configuration, it is difficult to determine the approach direction to the runway and the traveling route after takeoff in the case where a large number of distributed approach roadway indicator lights flash asynchronously. There was a difficulty. (2) Also, there was a lighting system configured to flash a large number of aerial beacon lights in a chain manner, but all were for straight approach. This aviation beacon lighting system for straight approach is to send a signal from the central supervisory control room to each approach road indicator light via the control line cable for multiple flash lights distributed in a narrow area, It is configured to flash in a chain.
