Question 29E5

SARTs (Search And Rescue Transponders) are emergency devices designed to aid in location by producing a distinctive signal on X-band radar. * **A) Incorrect:** Conducting an "operational test with several vessels to determine effective transmitting range" is not a valid or practical maintenance function. SART range is specified by design standards and regulations, and such extensive, multi-vessel testing is disruptive, could cause confusion, and is not a routine procedure for onboard crew. SARTs are not meant for routine, wide-area performance checks by users. * **B) Correct:** Visual inspection of the container for damage is a fundamental part of maintaining any safety equipment. Damage could compromise its watertight integrity or ability to deploy. * **C) Correct:** Batteries have limited lifespans, and their expiration date must be checked to ensure the SART will operate for the required duration in an emergency. The lanyard is critical for proper deployment and securing the device. * **D) Correct:** Most SARTs have a "test mode" that allows a brief, low-power activation to verify their response on the ship's own X-band radar. This confirms the transponder is functioning without transmitting a full distress signal or interfering with other vessels.
