🔍 Key Concepts

• Distress signals listed in the Navigation Rules Annex IV • Differences between distress, maneuvering, and warning signals • Use of shapes and colors (orange background, black symbols) in emergency signaling

💭 Think About

• Look up Annex IV of the Navigation Rules and see which specific signal is described as an orange flag with a black circle and square. • Ask yourself: is this the kind of signal a vessel would use for routine maneuvers or communication, or is it reserved for an emergency situation? • Consider where and when you would realistically see this flag used: during normal navigation, during a course change, or when assistance is needed?

✅ Before You Answer

• Verify in Navigation Rules – Annex IV (Distress Signals) whether an orange flag with a black circle and square is listed there. • Confirm whether maneuvering or course-change signals are normally given by sound signals or lights, rather than special flags like this. • Check if there is any separate, standard flag used only to "ask to communicate" with another vessel, and whether it matches the orange/black description.
