🔍 Key Concepts

• Ramark (radar marker beacon) function and purpose • Difference between bearing and range information on a PPI (plan position indicator) • How radar beacons (ramark vs racon) appear on radar displays

💭 Think About

• Ask yourself: does a ramark mainly help you identify a bearing, a range, or a precise position? • Compare each answer choice to what a line, circle, or coded signal would tell you about the target on the PPI. • Think about how a continuous signal transmitted on a fixed bearing from shore would logically paint on a rotating radar display.

✅ Before You Answer

• Confirm whether a ramark provides bearing-only information or both bearing and range. • Check which answer choice’s pattern would be fixed in bearing but extend across a range scale on the PPI. • Verify how a racon display differs from a ramark, so you don’t mix up the two in how they appear.
