Question 1454Navigation General70% to pass

When making landfall at night, you can determine if a light is a major light or an offshore buoy by _______________.

AI Explanation
The correct answer is C) checking the period and characteristics against the Light List. To identify a light as a major light or an offshore buoy, the key is to check the light's characteristics, such as its rhythm, intensity, and color, against the information provided in the Light List. The Light List contains detailed information about all navigational lights, including their locations, descriptions, and identifying characteristics. By comparing the observed light to the details in the Light List, you can determine whether it is a major light or an offshore buoy. The other options are not as reliable. The intensity of the light (A) can be affected by various factors, and the color alone (B) may not be enough to distinguish between different types of lights. While all the options (D) can potentially provide some information, checking the Light List is the most reliable way to positively identify the type of light you are observing.
