2.24.10 How to set a collision alert (CPA/TCPA alert)
To avoid collision with other ships, preset a threshold for CPA (Closest Point of
Approach to own ship by other ships) and TCPA (Time to Closest Point of Approach). If
both the CPA and TCPA of a tracking target becomes smaller than these two thresholds,
the target is recognized as a dangerous target (lit in red) and an alert message appears
simultaneously in the “ALERT LIST” window. If both the CPA and TCPA of a sleeping
target becomes smaller than the thresholds, the target is automatically activated to
become a dangerous target.
To silence the aural alarm and erase the alert message, press any key on the key pad.
The dangerous target remains displayed until the dangerous state is removed.
