- Q421 - Navigation Problems: Chart Plot
21. The Light List indicates that a light has a nominal range of 20 miles and is 52 feet (16 meters) high. If the visibility is 20 miles and your height of eye is 20 feet (6 meters), at what approximate distance will you sight the light?
The light will be sighted at approximately 13.5 nautical miles. The Earth's curvature, determined by the observer's and light's heights, limits visibility, as this geographic range is less than the light's nominal range.
