Accepted Answer

Option A: Great circle to LAT 51&deg;00'N, LONG 178&deg;00'W, parallel sailing for 80 miles, then great circle to the via point. When a great circle track exceeds desired latitude limits, composite sailing is employed. By plotting a great circle to the limiting parallel, steaming along that parallel, and then proceeding via a second great circle, the navigator ensures the most direct, safe route while avoiding hazardous high-latitude weather conditions.
