Navigation Problems USCG Question #814 (Set 24)

You are planning a voyage from departure Seattle (LAT 48°30'N, LONG 125°00'W) to a position at LAT 44°00'N, LONG 161°00'E. Which statement is TRUE? (Use gnomonic chart WOXZC 5270.)

Official USCG Answer & Rule Citation

Correct Answer: Option B — Military exercises north of 53°N, between 150°W and 165°W, will not affect your voyage.

According to Bowditch, gnomonic projection charts depict great circles as straight lines. Analyzing the geographic coordinates and chart WOXZC 5270 confirms that military warning areas between 150°W and 165°W lie entirely clear of the calculated transpacific great circle track between Seattle and the specified Asian position.
