ｄ 不動光の光度及び明滅の最大光度は、方位角において、光源の中心を含み、離陸若しくは着陸の経路を含む鉛直面又は当該経路に平行な鉛直面から左右それぞれ三度までの範囲及び航空緑と航空赤との境界面の上下それぞれ二度までの範囲では九千カンデラ以上、方位角において、光源の中心を含み、離陸若しくは着陸の経路を含む鉛直面又は当該経路に平行な鉛直面から左右それぞれ十五度までの範囲及び航空緑と航空赤との境界面の上下それぞれ十度までの範囲では三百七十五カンデラ以上であり、かつ、離陸若しくは着陸の経路を含む鉛直面又は当該経路に平行な鉛直面と航空緑と航空赤との境界面の交線に直交する平面における光柱の断面は、楕円形であること。
d. The maximum light intensity of a constant light and a blinking light shall be such that in the azimuth angles, a range within 3 degrees each leftward and rightward from a vertical plane comprising the light source center and take-off or landing path, or a vertical plane parallel to said path, and a range within 2 degrees upward and downward from the boundary plane between green and red, the intensity being 9,000 candela or more and such that in the azimuth angles, a range within 15 degrees each leftward and rightward from a vertical plane comprising the light source center and take-off or landing path, or a vertical plane parallel to said path, and a range within 10 degrees upward and downward from the boundary plane between green and red, the intensity being 375 candela or more, and, the cross-section of the anode light in the plane perpendicularly intersecting the crossing line of a vertical plane comprising the take-off or landing path or a vertical plane parallel to said path and the boundary plane between green and red shall be oval. - 日本法令外国語訳データベースシステム
