🔍 Key Concepts

• Running fixes and lines of position (LOPs) from multiple bearings to lights • Difference between position information (where you are) vs motion information (course made good, set and drift) • What information a single 3‑bearing fix at one time can and cannot tell you

💭 Think About

• If you plot the three simultaneous bearings, what do you actually get on the chart: a fix, a trend, or just one point? • Which of the answer choices require information about conditions over time (before and after 0415), and do you see that time‑history information in the question? • Ask yourself: from one plotted fix alone, can you determine whether you are left/right of track, what the depth is, or how the current compared to prediction—what extra data would each of those require?

✅ Before You Answer

• Check which choices require soundings or depth information—is any depth or charted sounding given in the problem? • Check which choices require comparison to a planned track or predicted current—has the planned track line or predicted set/drift actually been stated? • Verify which option could be directly supported by a single fix at 0415 using only the three bearings provided.
