🔍 Key Concepts

• Dead reckoning (DR) position at a given time and how it affects sunrise time at your location • Using the Nautical Almanac sunrise/sunset tables and interpolating for latitude and longitude • Converting between GMT/UTC, LMT (Local Mean Time), and Zone Time using the correct zone description

💭 Think About

• From the 0400 ZT DR position and course/speed, what is your vessel’s approximate position at the time of sunrise, and do you actually need to advance the DR, or is the change in position small enough to ignore for this problem? • After you obtain sunrise time from the almanac for the nearest whole latitude and standard meridian, how do you correctly apply longitude correction and then convert that time to your zone time? • Is your longitude east or west of the standard meridian, and does that make your local sunrise earlier or later than the tabulated value?

✅ Before You Answer

• Confirm which time scale the Nautical Almanac sunrise time is given in (usually GMT/UT) before doing conversions • Check your zone description (ZD) sign and whether you should add or subtract it when converting between UT and zone time • Verify that your longitude correction is applied in the correct direction: east longitudes make LMT later, west longitudes make LMT earlier relative to UT
