What does ELT stand for?

• A. Emergency Lighting System
• B. Emergency Locator Transmitter
• C. Emergency Life Support
• D. Emergency Luggage Tag

Answer: (B)

ELT refers to the device on an aircraft that automatically or manually sends a distress signal to help rescue teams locate the aircraft after an incident. It stands for Emergency Locator Transmitter, the system pilots and crew rely on to trigger search-and-rescue efforts quickly, typically broadcasting on standard emergency frequencies to satellites and receivers.

Other options describe different things entirely: an Emergency Lighting System provides cabin illumination during power loss, a term like Emergency Life Support isn’t a standard onboard system, and an Emergency Luggage Tag isn’t a safety device. So the correct interpretation is Emergency Locator Transmitter.
