What is the role of the Emergency Locator Transmitter?

• A. It emits emergency signals activated by impact or manually.
• B. It powers the cabin lighting.
• C. It controls the air conditioning.
• D. It provides in-flight communications.

Answer: (A)

The Emergency Locator Transmitter is a distress beacon that helps rescuers locate an aircraft after an emergency. It activates automatically on a crash impact or can be turned on manually by the crew, and it broadcasts emergency signals to alert search-and-rescue teams. Those signals travel via dedicated distress frequencies and the COSPAS-SARSAT satellite system, guiding rescuers to the aircraft’s location. It doesn’t power cabin lighting, control air conditioning, or handle in-flight communications, which is why the other roles don’t fit.
