USCG Exam PracticeRunning fix from a single object
A running fix is BEST described as the intersection of two lines of position where the first LOP has been:
- A. Observed simultaneously with the second LOP from two different objects
- ✓ Advanced along the DR track to the time of the second observationCorrect
- C. Corrected for estimated set and drift before being plotted
- D. Taken from the beam-most object and held fixed until the second bearing
Why B 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 defines this procedure explicitly.
