Question 38 Deck Safety

The correct answer is D) All of the above. A SART (Search and Rescue Transponder) is designed to respond to interrogation by 9 GHz radar signals, which are typically used by maritime and aviation search and rescue radar systems. The SART will respond when interrogated by a radar signal with a minimum power output of 10,000 watts, and when the searching vessel or aircraft is within a 30 nautical mile range and 3,000 feet altitude. This allows the SART to be detected by the searching radar system and help guide the rescue team to the distressed vessel's location. The other options are incorrect because they do not fully capture the conditions that will cause a SART to operate in the active mode, as described in the correct answer.
