Your 0830 DR position is LAT 27°33'S, LONG 79°17'E. Your vessel is on a course of 066°T, at a speed of 19.5 knots. Determine the time of LAN on 10 December.

Question

Your 0830 DR position is LAT 27&deg;33'S, LONG 79&deg;17'E. Your vessel is on a course of 066&deg;T, at a speed of 19.5 knots. Determine the time of LAN on 10 December.

Accepted Answer

Option A: 1131. To find the zone time of LAN, apply the longitude factor (4 minutes per degree) and the daily equation of time from the Nautical Almanac. Adjust the estimated time for vessel displacement along its course line between the DR time and the transit.
