Why is it important to limit the duration of testing a SART?

Correct Answer: Option B — Testing a SART should be performed only in a controlled environment, as a test signal may be misinterpreted as a genuine Distress situation.

SART signals are designed to be indistinguishable from actual distress transmissions on a radar PPI. To prevent unnecessary search and rescue mobilization, functional testing must be strictly limited and performed only in controlled environments where the signal cannot be misinterpreted by other vessels as a genuine emergency.
