USCG Exam PracticeRunning fix from a single object
A navigator obtains a radar range and bearing to a single charted object. This observation produces which type of position?
- A. A running fix, because two separate measurements are combined
- B. A dead reckoning position
- ✓ A direct fixCorrect
- D. An estimated position only, because radar bearing accuracy is insufficient
Why C is correct
Range and bearing to a target from marine radar give a direct fix. Both measurements are taken simultaneously from the same observation, satisfying the requirement for a fix without advancing any LOP. (Bowditch Ch. 13 §1301)
