USCG Exam PracticeDanger bearings and danger circles
Between fixes, a navigator uses danger bearings and clearing lines primarily to:
- A. Advance the first LOP along the DR track to obtain a running fix
- ✓ Keep the vessel off charted hazards when a full simultaneous fix is not availableCorrect
- C. Determine the vessel's speed made good over the ground
- D. Identify the beam-most object for the strongest LOP crossing angle
Why B is correct
Bowditch Ch. 7 §707 states that danger bearings and clearing lines supplement the fix to keep the vessel off charted hazards between fixes. Advancing an LOP describes a running fix, which is a separate technique.
