USCG Exam PracticeRunning fix from a single object
Which statement correctly describes the 'doubling-the-angle' technique for obtaining a running fix from a single object?
- A. The distance run between the two bearings equals the distance to the object at the first bearing
- ✓ The distance run between the two bearings equals the distance to the object at the second bearingCorrect
- C. The two bearings must be taken simultaneously to produce a valid fix
- D. The technique requires the relative bearing to remain constant between observations
Why B is correct
In the doubling-the-angle technique, two relative bearings are taken to a single object; the distance run between them equals the distance to the object at the time of the second bearing. (Bowditch Ch. 7 §703)
