🔍 Key Concepts

• How radar range measurements appear when plotted from your vessel to a fixed object on a chart • The geometric shape made by all points at the same distance from a single point • Difference between range (distance) and bearing (direction) as types of lines of position (LOPs)

💭 Think About

• If you know you are exactly X miles from a light, what are all the possible positions you could be in around that light? Visualize that on the chart. • Compare how a bearing gives a line that passes through the object versus how a range gives all points at an equal distance from it. • Think about what shape is formed on paper if you put a pin at the light and use a compass set to the radar range.

✅ Before You Answer

• Clarify that a radar range LOP is based only on distance, not direction. • Recall that all points equidistant from a single point form a specific geometric shape. • Make sure you are not confusing this with systems (like LORAN or GPS) that use difference in distance from two points, which produce a different curve.
