On 14 October your 0800 ZT DR position is LAT 28°22.0'N, LONG 161°17.0'E. Your vessel is on course 116°T at a speed of 17.5 knots. What is the ZT of local apparent noon (LAN)?
Official USCG Answer & Rule Citation
Correct Answer: Option D — 1156
In accordance with Bowditch celestial navigation and time arc principles, compute the vessel's interpolated longitude at LAN based on course and speed. Factoring in the equation of time for October 14 establishes the zone time of LAN at 1156.
