The ELT built into the life raft is one-way.

• A. Not stated
• B. False
• C. Both
• D. True

Answer: (D)

The main idea here is that the ELT built into a life raft functions as a one-way distress beacon. Its job is to transmit a signal that search-and-rescue authorities can receive and use to locate you, not to receive replies or instructions. When activated, it broadcasts a beacon (often with a 406 MHz signal to satellites and a 121.5 MHz homing signal) so rescuers can pinpoint your location, and it does not engage in two-way communication. This one-way design keeps the device simple, reliable, and capable of operating automatically if you’re unable to manually activate it. Note that a life raft may also include separate two-way communication gear (like a survival radio), but the ELT itself remains a one-way transmitter.
