Question 1473Navigation General

The correct answer is D) line of position. When a true bearing of a charted object is plotted on a nautical chart, it establishes a line of position (LOP). A line of position represents the direction from the observer's position to the charted object, and indicates that the observer's position lies somewhere along that line. This is a fundamental concept in celestial navigation and other forms of position-fixing. The other answer choices are incorrect because: A) a range is the distance between two points, not established by a bearing; B) a relative bearing is the angle between the ship's heading and the object, not a true bearing; and C) a fix requires the intersection of two or more LOPs to determine a precise position.
