In navigation, which statement best describes the purpose of a back azimuth?

• A. To set a new course toward the objective.
• B. To verify your position by checking the direction back to your starting point and staying on course.
• C. To measure your pace count.
• D. To identify terrain features.

Answer: (B)

The idea here is using a back azimuth to verify your position and stay on the intended line of travel. A back azimuth points from your current location back to where you started, so you can compare it with the known direction to your origin on your map. If your compass shows that direction and your land features line up with the map, you’re on course and can trust your position. If it doesn’t match, you’ve likely drifted or veered off the line, and you need to adjust. This isn’t about setting a new course toward the objective, measuring pace count, or identifying terrain features. Those tasks are handled by other bearings, pace cues, and terrain observation, respectively.
