Navigation General · Aids to Navigation — RACON

- AA weather front
- BA solid filled circle
- CA coded (Morse) signal extending radially outward from the beacon's position✓ Correct
- DA flashing light only
Explanation
When triggered by a ship's radar, a RACON transmits a response that paints a Morse-coded line extending outward (away from own ship) from the beacon's location on the radar screen, helping identify key marks, bridges, and landfalls.
