Q

The light characteristic of flashing is used in the Aids to Navigation System on the Western Rivers for lights on __________.

🔍 Key Concepts

• Western Rivers Aids to Navigation System and how it differs from IALA-B ocean/coastal systems • Meaning of flashing light characteristic on river aids vs. fixed or quick flashing • How right/left descending bank is defined (looking downstream)

💭 Think About

• Ask yourself: On the Western Rivers, what does a flashing light on a bank marker tell the mariner about that side of the channel? • Think about how the system helps a vessel going downstream at night to quickly identify which bank they are closest to. • Consider whether flashing lights are normally used to mark mid-channel, preferred channels, or specific banks in this special river system.

✅ Before You Answer

• Be clear on the definition of descending bank (direction of river flow, not direction of your vessel). • Confirm from Western Rivers guidance which side’s bank markers are given flashing lights for quick identification. • Verify that preferred channel buoys and daymarks with no lateral significance use different light characteristics than simple flashing in this system.
