Question

On 26 September your 0830 DR position is LAT 26&deg;04.0'N, LONG 129&deg;16.0'W. Your vessel is on a course of 119&deg;T at a speed of 20.0 knots. What is the zone time of local apparent noon (LAN)?

Accepted Answer

Option A: 1124. Local Apparent Noon occurs when the Sun's LHA is 0°. Calculate the time of LAN by applying the longitude correction (4 minutes per degree) to the 1200 GMT meridian passage time. Adjusting for the vessel's DR longitude and speed, the zone time of LAN is determined to be 1124.
