What does the alarm panel on the ARPA display indicate?

In ARPA, the alarm panel is the tool that flags potential collision risks. It shows active alerts for targets that meet risk criteria and uses color coding to make high‑risk targets stand out, so you can quickly see which vessels require action. This panel focuses on threat status, not just raw measurements. Weather overlays and navigation charts are separate features on the radar system. Weather overlays would display precipitation or other environmental data, and charts are used for navigation, not for highlighting collision threats. The alarm panel’s job is to draw attention to targets that could be dangerous and guide your avoidance decisions.
