Q

All straight lines represent great circle tracks on a chart based on which projection?

🔍 Key Concepts

• Difference between great circle and rhumb line (loxodrome) tracks • Which chart projection shows great circles as straight lines • Typical use of Mercator vs. Gnomonic charts in ocean navigation

💭 Think About

• On your standard Mercator navigation chart, do long ocean routes (great circles) usually appear as curved or straight? Think about what you were taught to transfer routes between charts. • Which projection do ocean navigators often use specifically to plot the initial great-circle route before transferring waypoints back to a Mercator chart? • Among the listed projections, which one is known for making shortest-distance (great circle) routes easy to draw as straight lines?

✅ Before You Answer

• Identify which projection is specifically associated with great circle routes appearing as straight lines. • Recall that on a Mercator chart, a straight line represents a rhumb line, not a great circle. • Eliminate any projection you know is mainly for visual/earth-like appearance rather than precise navigation of great circles.
