Title 14 - Aeronautics and Space
No position light intensity may exceed the applicable values in the following table, except as provided in §27.1389(b)(3). Where— (a) Area A includes all directions in the adjacent dihedral angle that pass through the light source and intersect the common boundary plane at more than 10 degrees but less than 20 degrees, and (b) Area B includes all directions in the adjacent dihedral angle that pass through the light source and intersect the common boundary plane at more than 20 degrees.
