The Light List indicates that a light has a nominal range of 8 miles and is 48 feet(14.6 meters) high. If the visibility is 6 miles and your height of eye is 35 feet(10.7 meters), at what approximate distance will you sight the light?

Correct Answer: Option B — 5.9 nm

Luminous range is the maximum distance a light can be seen based on intensity and current visibility. Since the visibility (6 nm) is less than the nominal range (8 nm), the light will be sighted at the visibility distance, provided the geographic range is not the limiting factor.
