🔍 Key Concepts

• SART (Search and Rescue Transponder) purpose and how it reacts to being hit by a 9 GHz / 3 cm X‑band radar • What kind of local indication the survivor gets from the SART itself (on the raft) versus what appears on the ship’s radar screen • Difference between identification data (like GPS position, ID, serial number) and a simple “I have been triggered” indication

💭 Think About

• Ask yourself: when you are in the raft, what simple confirmation do YOU need to know that a nearby ship’s X‑band radar has activated your SART? • Think about which of the options would realistically require a screen/GPS versus a very basic, low‑power device meant only to be seen on another vessel’s radar. • Which choices describe information that would logically appear on the ship’s radar display, not on the SART unit in your liferaft?

✅ Before You Answer

• Verify that a SART is designed to respond specifically to 9 GHz (3 cm) X‑band radar, not to provide full GMDSS‑style data like GPS position. • Check which answers require a built‑in display with detailed text or numbers, and ask whether standard SARTs actually have this kind of display. • Confirm which option describes a simple local alert from the unit itself, rather than advanced data output.
