USCG Exam PracticeChart symbols and abbreviations (Chart No. 1)
A chart depicts two aids to navigation. The first is labeled in italic type with a small circle position symbol; the second is labeled in italic type with a star position symbol. What can be correctly concluded about these two aids?
- ✓ Both are aids to navigation; the first is a buoy and the second is a lighthouseCorrect
- B. The first is a buoy and the second is a geographic landmark, not an aid to navigation
- C. Both are lighthouses; the circle denotes a minor light and the star denotes a major light
- D. The italic label on the second aid indicates it is a private aid not maintained by the USCG
Why A is correct
Italic labeling identifies both features as aids to navigation. The position symbol distinguishes the type: a small circle marks a buoy (centre = charted position) and a star marks a lighthouse (centre = charted position). Upright lettering would indicate a non-aid geographic feature. (Light List — Italicised Aid Names; Light List — Position Symbol)
