Question 1798Navigation General70% to pass
In illustration D051NG below, why was the position labeled "D" plotted?
AI Explanation
The correct answer is A) a dead reckoning position is plotted for each course change.
In navigation, a dead reckoning position is plotted at regular intervals, typically after each course change, to keep track of the vessel's position. This allows the navigator to monitor the vessel's progress and make any necessary adjustments to the course or speed. The position labeled "D" in the illustration D051NG was likely plotted to record the vessel's position after a course change.
The other options are incorrect because they do not fully explain the purpose of plotting the position labeled "D". Option B is incorrect as it does not explain why a dead reckoning position would be plotted. Option C is incorrect as it refers to plotting a position within 30 minutes of a running fix, which is not the same as plotting a dead reckoning position after a course change.
