Q

At 2259 Cape Henry Light bears 250°T, Chesapeake Light bears 122°T, and North Chesapeake Entrance Lighted Whistle Buoy "NCA" has a radar range of 1.8 miles. Which statement is TRUE?

🔍 Key Concepts

• Simultaneous true bearings to fixed objects give you a fix on the chart • How to determine a course made good from a track line between two known positions • Use of light sectors and chart notes (e.g., red sector limits, submarine transit lanes) from the chart/Light List rather than pure calculation

💭 Think About

• If you plot the two true bearings of Cape Henry Light and Chesapeake Light on the appropriate chart, where is your fix relative to those aids and to Buoy NCA? • From that plotted position, which of the answer choices can you check directly on the chart (distance to an aid, sector color, special-purpose areas, or track/course)? • Ask yourself: do the data given (two bearings at one time and one radar range) actually allow you to determine a course made good, or only your position at that instant?

✅ Before You Answer

• On the chart, verify the color sectors and bearing limits of Cape Henry Light and see which area corresponds to your fixed position • On the chart, measure the distance from your fix to Chesapeake Light and compare to option A • Check the chart notes for any submarine transit lanes near the Chesapeake entrance and see whether your plotted fix lies inside one
