🔍 Key Concepts

• Geographic range vs. luminous range of a light • Using the distance to the light from your DR (dead reckoning) position to determine sighting time • Converting distance at a given speed into time of arrival at the visibility limit

💭 Think About

• How far are you from New Haven Light at 0500 based on your DR track and speed? • At 10 miles visibility, at what distance off the light should you first be able to see it, and at what time will you reach that distance? • Are you limited by the earth’s curvature (geographic range) or by the 10-mile visibility (luminous range) in this problem?

✅ Before You Answer

• Confirm your speed in knots and the distance run per 6 minutes • Check the distance from your DR position at each listed time (0500, 0508, 0514) to New Haven Light • Verify whether the calculated distance at each time is less than, equal to, or greater than 10 nautical miles
