On 19 November your 0200 zone time DR position is LAT 18°41'N, LONG 150°37'E. You are on course 014°T at a speed of 18 knots. You observed 3 celestial bodies. Determine the latitude and longitude of your 0600 running fix.

🔍 Key Concepts

• Dead reckoning (DR) track and advancing an LOP to a later time • Using speed, time, and course to advance a DR position: 4 hours at 18 knots on course 014°T • Effect of advancing multiple celestial LOPs to form a running fix

💭 Think About

• From 0200 to 0600, how far do you travel along 014°T at 18 knots, and in what direction is that movement on the chart? • If your running fix is based on LOPs advanced to 0600, should the final position be exactly on the DR track or slightly off it? Why? • Compare each choice with the 0600 DR position you would compute; which answers are clearly too far away or in the wrong direction from the DR?

✅ Before You Answer

• Compute the 0600 DR position first using speed–time–distance and course made good • Check whether each option is north or south and east or west of your 0600 DR position and by roughly how many miles • Verify that the most reasonable answer should differ from the DR by an amount consistent with normal celestial running-fix intersections (not tens of miles away unless there’s a clear reason)
