🔍 Key Concepts

• Dead reckoning (DR) definition and what inputs it uses • Difference between DR position and estimated position (EP) • How current, wind, and leeway affect different types of plots

💭 Think About

• Ask yourself: When you do a pure DR plot, what information are you allowed to use—only what you STEER, or also what the water and wind do to you? • Think about whether DR depends on magnetic vs true courses, or if it can use either as long as you’re consistent. • Consider: Is DR mainly for when you can see land, or for when you cannot see land?

✅ Before You Answer

• Verify what a textbook definition of DR says about using or ignoring current and leeway. • Check whether a DR track has to start from an assumed position or from a known fix. • Confirm whether DR requires magnetic courses only, or if that statement sounds too restrictive to be correct.
