Federal Aviation Regulations
Sec. 25.1395 — Maximum intensities in overlapping beams of forward and rear position lights.
No position light intensity may exceed the applicable values in the following table, except as provided in §25.1389(b)(3).| Overlaps | Maximum intensity | |
|---|---|---|
| Area A (candles) | Area B (candles) | |
| Green in dihedral angle L | 10 | 1 |
| Red in dihedral angle R | 10 | 1 |
| Green in dihedral angle A | 5 | 1 |
| Red in dihedral angle A | 5 | 1 |
| Rear white in dihedral angle L | 5 | 1 |
| Rear white in dihedral angle R | 5 | 1 |
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.
