Question 324Navigation General
70% to passWhat 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".
A
18.8 nm
B
19.3 nm
C
20.3 nm
D
24.8 nm
AI Explanation
The correct answer is B) 19.3 nm. The geographic range of a lighthouse can be calculated using the formula: Range (in nautical miles) = 2.23 x √(height of eye in feet). With a height of eye of 40 feet, the formula yields a range of 19.3 nautical miles. The other options are incorrect because: A) 18.8 nm is too low C) 20.3 nm is too high D) 24.8 nm is significantly too high and outside the expected range for a lighthouse with a 40-foot height of eye.
