Q

When possible, a DR plot should always be started from where?

🔍 Key Concepts

• Dead Reckoning (DR) plot meaning and purpose • Difference between assumed, estimated, and known (fix) positions • How DR error grows over time from the starting point

💭 Think About

• Think about which type of starting position gives you the smallest initial uncertainty in your track line. • Ask yourself how DR errors behave: do they get bigger or smaller the farther you go from your start point? • Consider what a DR plot is meant to do in relation to your last precise fix on the chart.

✅ Before You Answer

• Identify which choice represents a position that has been fixed on the chart by reliable observations. • Eliminate any options that would add extra uncertainty right at the start of the DR. • Confirm in your mind how DR error propagates outward from the point where you begin plotting.
