🔍 Key Concepts

• Plotting great-circle vs. rhumb line distances on the given chart or plotting sheet • Using latitude scale on the sides of the chart to measure distance in nautical miles • Converting minutes of latitude into nautical miles (1′ of latitude = 1 NM)

💭 Think About

• From your 0731 fix, how will you draw and label the straight-line track to Wilmington, NC on the chart? • After drawing the line, what specific part of the chart should you use to measure the distance accurately—top/bottom or left/right borders? Why? • Once you have the distance in nautical miles, how will you compare that number to the multiple‑choice answers given in statute miles or nautical miles?

✅ Before You Answer

• Be sure you are measuring along a meridian of latitude, not the longitude scale, when converting minutes to miles • Check whether the answer choices are in nautical miles or statute miles, and convert if needed • Confirm you are using the correct 0731 fix (right position, right time) before drawing the line to Wilmington
