What is the approximate geographic range of Horton Point Light, NY, if your height of eye is 40 feet (12.2 meters)? Refer to "Reprints from the LIGHT LISTS AND COAST PILOTS".

🔍 Key Concepts

• Difference between geographic range and luminous/nominal range of a light • How to use the Light List table for distance to the horizon based on height of eye and height of light • That the total geographic range is based on adding observer’s horizon distance and light’s horizon distance

💭 Think About

• First, look up Horton Point Light in the Light List and note the height of the light in feet or meters. • Use the distance-to-horizon table (or formula) to find the range for your height of eye (40 ft / 12.2 m). • Then find the distance to the horizon for the height of the light, and combine these two distances to estimate the geographic range. Does that combined value line up with one of the answer choices?

✅ Before You Answer

• Verify you are using geographic range, not nominal or luminous range, when comparing with the answers. • Double-check you used the correct height of the light from the Light List entry for Horton Point Light, NY. • Confirm you converted units correctly (feet/meters) and matched them to the correct row/column in the distance-to-horizon table before adding the two distances.
