At what point does a SART begin transmitting?
Official USCG Answer & Rule Citation
Correct Answer: Option C — If it has been placed in the "on" position, it will respond when it has been interrogated by a 9-GHz radar signal.
A SART does not continuously radiate power; once manually switched from standby to active, it remains in a receiving state until triggered by an interrogating 9-GHz X-band radar signal.
