Q

ECDIS must give an alarm for which of the following cases?

🔍 Key Concepts

• IMO ECDIS performance standards (IMO Resolution MSC.232(82)) alarm categories • Difference between alarms and simple indications on ECDIS • What ECDIS is designed to warn about in relation to safety contour, route monitoring, and prohibited/danger areas

💭 Think About

• For each option (A–C), ask: Is this situation related to navigational safety limits that ECDIS is specifically required to monitor? • Think about what parameters the watch officer sets in ECDIS (time to danger, cross-track error limits, safety contour) and which of those are tied to mandatory alarms. • Consider whether ECDIS should warn you only for one or two of these hazards, or whether good design and IMO standards would require alarms for all similar safety‑critical events.

✅ Before You Answer

• Check in MSC.232(82) that crossing a safety contour must generate an alarm, not just a visual indication. • Verify that exceeding a route deviation limit (cross‑track error) during route monitoring must also cause an alarm condition. • Confirm whether entering or nearing a prohibited or danger area (e.g., restricted, caution, or no‑go area) is listed as an event that must trigger an alarm.
