🔍 Key Concepts

• Bearing from your vessel vs. bearing from the aid – if Chesapeake Light bears 091°T from you, what is the reciprocal bearing from the Light to you? • Range and distance on a chart – 1 minute of latitude ≈ 1 nautical mile; use this to approximate distances between candidate positions and the Light. • Plotting or mentally checking bearing – how does changing longitude slightly east or west affect the bearing from Chesapeake Light to your position?

💭 Think About

• First, think about where your vessel must lie relative to Chesapeake Light if the Light bears 091°T from you. Are you generally north, south, east, or west of the Light? • Next, convert the 091°T bearing from your vessel to the Light into the approximate direction from the Light to you. Which general quadrant around the Light does that place you in? • Then, using the differences in latitude and longitude for each option, estimate which point is about 10.5 nm from Chesapeake Light and lies on that reciprocal bearing.

✅ Before You Answer

• Verify the reciprocal bearing (add or subtract 180°) to get the direction from Chesapeake Light to your vessel. • Check that the chosen option is roughly 10.5 nm from Chesapeake Light using latitude differences (1' ≈ 1 nm) and adjusting longitude with cos(latitude) if you want more accuracy. • Confirm that the latitude and longitude changes for your choice put you in the correct quadrant (NE, NW, SE, SW) relative to Chesapeake Light given the reciprocal bearing.
