🔍 Key Concepts

• Great circle vs rhumb line appearance on gnomonic vs Mercator charts • Location of the vertex of a great circle between two given positions • How to check whether a plotted track passes within a given radius of a position (150 NM)

💭 Think About

• On a gnomonic chart the great circle is a straight line. How will that same line look when transferred to a Mercator chart between mid‑latitudes in the North Pacific—will it normally form an S‑curve or bend in just one sense? • Given the endpoints (Cape Flattery and Guam), roughly where in latitude and longitude would you expect the Northern Hemisphere vertex of the great circle—farther north than both points, or between their latitudes? • If you plot the straight great‑circle line on the gnomonic chart, does the point LAT 47°10'N, LONG 137°30'W lie close to this line? How could you use the chart’s scale to judge whether it is within 150 NM?

✅ Before You Answer

• On a gnomonic chart, great circles are straight; on a Mercator chart, great circles (except the equator and meridians) curve. • The vertex latitude of a great circle between two mid‑latitude points in opposite hemispheres of longitude is usually higher than the higher endpoint latitude—confirm this on the chart. • When checking the 150‑mile radius, use the chart’s latitude scale (1 minute = 1 NM) to estimate the distance from the exercise center to the plotted great‑circle line.
