🔍 Key Concepts

• Great-circle vs. rhumb-line (loxodromic) sailing on a gnomonic chart • How composite sailing limits latitude using a great-circle with a limiting parallel • Definition and location of a vertex of a great-circle track

💭 Think About

• Compare the starting and ending latitudes: does having nearly the same latitude automatically mean the great-circle looks like a parallel, or will it still curve noticeably on a gnomonic chart? • Think about where the vertex of a North Atlantic great-circle between these two longitudes would lie: will it be north or south of the endpoints, and roughly in what longitude range? • On a gnomonic chart, how do you transfer a great-circle track to a Mercator chart and how is the distance actually measured — is it taken directly on the gnomonic, or elsewhere?

✅ Before You Answer

• Verify how a great-circle appears on a gnomonic chart (straight line) versus on a Mercator chart (curved line) and where you actually measure distance. • Check whether a composite sailing is even necessary for this route by estimating the latitude of the great-circle vertex relative to a limiting parallel of 44°N. • Confirm the definition of the vertex longitude for a great-circle between similar latitudes and the approximate mid-Atlantic longitude between Cape May and Lisbon.
