🔍 Key Concepts

• Great circle vs. rhumb line tracks and how they appear on a gnomonic chart • How to locate the vertex and determine its latitude and longitude on a great circle • Plotting reported hazards (icebergs, shoals) and seeing whether the great circle passes within their stated limits

💭 Think About

• First, plot the great circle between the two positions on the gnomonic chart and mark several points along the track. What special point along the track should you locate to answer one of the options? • Compare the plotted track with the positions/limits of Cape Race ice reports and Sable Island shoal areas. Does the track actually pass close enough to either hazard to be a concern? • Think about how distance on a great circle is normally measured: do we use one special latitude only, or do we transfer segments to a different kind of chart? How would that affect which statement can be correct?

✅ Before You Answer

• Make sure you have clearly identified the vertex of the great circle and its longitude from the gnomonic chart before deciding on option C. • Verify on the chart whether the plotted track passes within the stated radii of the ice limits and Sable Island shoals before accepting options A or D. • Confirm from your plotting method how you actually measure great-circle distance: check whether it involves using 60-mile segments at a single latitude, or another standard procedure.

Question 1 of 20

You are planning a voyage by great circle from LAT 38° 00' N, LONG 73° 00' W to LAT 49° 00' N, LONG 06° 00' W. Which of the following statements is TRUE? (Use gnomonic tracking chart WOXZC 5274)

You will pass to the south of icebergs reported extending to 100 miles south of Cape Race Newfoundland.

The distance is measured in 60-mile segments using the length of a degree of latitude at the vertex.

You will reach the maximum northerly latitude at longitude 29° 45' W.

The shoals with a 25-mile radius around Sable Island will be a hazard.
