🔍 Key Concepts

• Gnomonic projection – how great circles and rhumb lines look on this type of chart • Difference between a great circle and a loxodrome (rhumb line) • How great circles appear on Mercator vs. gnomonic charts

💭 Think About

• Think about which type of projection is specifically used for plotting great circle routes and why navigators then transfer the track to another chart type • Ask yourself: on which type of chart does a great circle appear as a curve, and on which does it appear differently? • Consider what a loxodrome (rhumb line) looks like on various chart projections and whether that matches a great circle description

✅ Before You Answer

• Verify which line type (great circle or rhumb line) appears as a straight line on a gnomonic chart • Confirm whether a loxodromic curve is the same thing as a great circle (it is not) • Recall: on a Mercator chart, do great circles appear straight or curved? Use that contrast to guide your choice
