Q

Which is TRUE of a dead reckoning (DR) plot?

🔍 Key Concepts

• Dead reckoning (DR) definition and what is and is NOT included in it • Difference between DR position and estimated position (EP) (which uses set and drift) • Good piloting practice regarding when and how often to update your DR

💭 Think About

• Ask yourself: When you advance a DR, are you using only your course and speed through the water, or are you also correcting for current and wind? • Think about standard watchstanding practice: when do you customarily start or update a DR in relation to getting a fix? • Consider whether DR has to use magnetic, true, or can be either—what actually matters on the chart?

✅ Before You Answer

• Verify what information is used to plot a pure DR (course steered and speed, over a given time). • Distinguish carefully between DR and EP in your study materials—EP includes set and drift, DR does not. • Check standard piloting procedures for recommended frequency of DR updates and what event usually triggers beginning a new DR.
