USCG Exam PracticeRunning fix from a single object
A running fix differs from a standard fix primarily because the running fix is obtained when:
- A. Two or more LOPs are taken simultaneously from different objects
- B. Radar range and bearing are used together
- ✓ LOPs cannot be taken simultaneously and the first LOP is advanced along the DR track to the time of the second observationCorrect
- D. The vessel's course is changed between observations
Why C is correct
A running fix is obtained when LOPs cannot be taken simultaneously; the first LOP is advanced along the DR track to the time of the second observation, and their intersection is the running fix. (Bowditch Ch. 7 §702)
