Question 55Deck Safety70% to pass

You are the officer in charge of a navigational watch, what signal would indicate your 3 cm radar has interrogated a SART unit?

AI Explanation
The correct answer is A) a line of consecutive dots on the radar screen indicating the bearing of the unit. The reasoning behind this is that a SART (Search and Rescue Transponder) unit, when interrogated by a 3 cm radar, will respond with a series of 12 consecutive radar dots displayed on the radar screen. These dots will indicate the bearing of the SART unit relative to your vessel's position, allowing you to quickly locate the source of the distress signal. The other options are incorrect because: B) a flashing target is not the correct visual indication for a SART response, C) there is no audible signal through the GMDSS console, and D) the Automatic Identification System (AIS) is not involved in the detection of a SART unit by a 3 cm radar.
