Which warning is required by IMO performance standards?

The warning required by IMO performance standards focuses on keeping the navigator aware whenever the vessel’s own maneuver could change the collision risk picture. When your own ship changes course, the relative geometry to any targets shifts, so the calculated closest points of approach and times to closest point of approach must be updated. An automatic warning about a change in your own course prompts you to re-evaluate targets, CPA/TCPA, and potential actions to maintain safe separation. The other options describe alerts that aren’t the standardized self-movement warning: observer-set zone alarms, a fixed distance threshold, or a hardware fault warning. Those don’t consistently reflect the risk changes caused by your vessel’s maneuver, whereas a warning when your own ship changes course directly supports timely, active collision avoidance.
