Question 1 of 27070

🔍 Key Concepts

• Radar range arcs for a fix using three known objects • How to plot ranges from lights or buoys on the chart to find a position • Reading longitude accurately from the chart scale once the fix is plotted

💭 Think About

• How do you convert each radar range into something you can draw on the chart from each aid to navigation? • Once you have three arcs on the chart, where should your fix lie relative to those arcs, and how do you mark it? • After marking your fix, what is the careful step‑by‑step way to read the longitude value, including degrees and minutes, from the chart?

✅ Before You Answer

• Make sure the correct charted positions of York Spit Light, New Point Comfort Spit Light "2", and York Spit Swash Channel Light "3" are used • Verify that each radar range arc is drawn at the correct distance in nautical miles from each object • Double‑check the longitude reading: confirm the degree (°) and minute (') values match the meridians and that you are west (W) of the prime meridian
