USCG Exam Practice · Three-bearing fix and cocked-hat triangle

A fix obtained from two or more LOPs requires that those LOPs be taken in what manner?

  1. ASequentially, with the first LOP advanced along the DR track
  2. BFrom a single charted object observed twice
  3. CSimultaneously✓ correct
  4. DAt intervals no greater than five minutes apart

Why C is correct

Bowditch Ch. 7 §701 states that a fix is the intersection of two or more LOPs taken simultaneously. When LOPs cannot be taken simultaneously, the result is a running fix, which is less accurate.
