According to this proposal example, the individual support lights 1,
Since 1,1, ... are independent and portable, they are easy to transport and install, but all the support lights 1,1, ... emit light at the same timing and at a predetermined time interval. Although it can be shown, it cannot show the approach direction of the helicopter to the landing zone 2. Therefore, an approach direction indicator light for indicating the approach direction of the helicopter to the landing zone 2 must be installed separately from the plurality of support lights 1, 1 ,. Therefore, the entire set requires a plurality of support lights 1, 1, ... And a plurality of approach direction lights and their control units, which is also a large scale. It was
