Q

At 2027 you obtain a radar range to Shagwong Point of 3.4 miles and a tangent bearing to the east end of Long Island of 172°T. Which statement is TRUE?

🔍 Key Concepts

• Use of radar range and visual tangent bearing to fix your position on the chart • Difference between course made good vs. speed made good over a time interval • Chart symbols and limits of a precautionary area around Shagwong Point / eastern Long Island

💭 Think About

• Plot your DR (dead reckoning) from 1949 to 2027, then plot the 3.4-mile range to Shagwong Point and the 172°T tangent bearing to the east end of Long Island. Where does that put you relative to your DR track? • From the distance run between your 1949 position and your 2027 fix, and the elapsed time, what speed would that imply? Does it reasonably match any of the statements? • Check the chart around your 2027 fix: are you actually within the limits of a precautionary area, or outside it?

✅ Before You Answer

• Confirm the elapsed time between 1949 and 2027 and convert it correctly to hours before checking any speed answer. • Verify the direction of set and drift implied by the difference between your DR and fix: does the fix fall to the right or left of your intended track? • Carefully trace the boundaries of any precautionary area on the chart and see if your 2027 fix is clearly inside or clearly outside.
