🔍 Key Concepts

• Purpose of the Light List for inland rivers, especially the Mississippi River System • Typical contents: information about aids to navigation (lights, buoys, daybeacons, ranges) • Things that are usually found in other Coast Guard publications or broadcasts instead of the Light List

💭 Think About

• Which option sounds more like a navigation aid description versus an operational or information service? • Ask yourself: what information does a mariner need about each individual aid to navigation listed? • Which choice seems like it would change frequently and therefore would be better handled by broadcasts or separate notices rather than a printed/reference book?

✅ Before You Answer

• Check which items are clearly directly tied to each light or buoy (e.g., characteristics, range/visibility, location). • Identify which choice is about Coast Guard communication schedules rather than fixed navigation aid data. • Consider which information would be more appropriate in Notices to Mariners or radio broadcasts, not a static Light List.
