Q

Which aid is NOT marked on a chart with a magenta circle?

🔍 Key Concepts

• Magenta chart symbols for electronic and radio aids to navigation • How radar-related aids vs. radio beacons are shown on NOAA/USCG charts • Differences in chart depiction between land-based visual lights and electronic/radio signals

💭 Think About

• Look at which of these aids primarily involves radio or radar signals that mariners tune in or detect electronically, versus a purely visual aid • Think about which items are usually shown as special-purpose symbols in black or other colors, rather than highlighted in magenta • Ask yourself: which aid would be obvious to the eye from a long distance and already has its own prominent light symbol, so it might not need a magenta circle?

✅ Before You Answer

• Check in a chart No. 1 (U.S. Chart Symbols) which aids actually use a small magenta circle as part of their symbol • Verify which of the choices are electronic/radio navigation aids and which is primarily a visual light for aircraft • Confirm whether a shore radar installation is indicated the same way as a radar transponder beacon (racon) or radio beacon on charts
