What term represents the distance between two terrestrial objects?

• A. Bearing
• B. Heading
• C. Range
• D. Course

Answer: (C)

Range is the straight-line distance separating two terrestrial points. It tells you how far apart they are, independent of direction. That’s different from bearing, which is the direction from one object to the other, and from heading or course, which describe the observer’s orientation or intended path rather than the separation itself. For example, two towns might be 12 miles apart; that 12-mile value is the range between them. On a chart or map, you determine range by measuring the line-of-sight distance between the two points, then converting that map distance to real-world miles or kilometers.
