USCG Exam PracticeLatitude, longitude, and geographic coordinates
In confined waters where electronic positioning is obstructed by terrain, which navigation method is identified as the primary technique?
- ✓ Piloting, using landmarks, aids to navigation, and soundingsCorrect
- B. Dead reckoning, applying course and distance from the last known fix
- C. Celestial navigation, using sun and star observations for position lines
- D. Electronic navigation, switching to an alternate frequency or channel
Why A is correct
Bowditch Ch. 1 §103 identifies piloting — navigation by reference to landmarks, aids to navigation, and soundings — as the primary method in confined waters where dead reckoning alone is insufficient and electronic positioning may be obstructed.
