USCG Exam PracticeRunning fix from a single object
When applying the doubling-the-angle technique, what does the distance run between the first and second bearing equal?
- A. The distance from the vessel's DR position to the charted object at the time of the first bearing
- ✓ The distance from the vessel's DR position to the charted object at the time of the second bearingCorrect
- C. Half the distance to the charted object at the time of the second bearing
- D. The distance from the advanced first LOP to the second LOP along the course line
Why B is correct
Bowditch Ch. 7 §703 states that in the doubling-the-angle technique, the distance run between the two bearings equals the distance to the object at the second bearing, giving the navigator a distance-off at that moment.
