Which of the following indicates the Emergency Locator Transmitter is correctly set up?

• A. Toggled switch in off position
• B. Toggle switch in armed position
• C. Not secured in holder
• D. Battery low indicator active

Answer: (B)

The Emergency Locator Transmitter (ELT) is a crucial device in aviation used for search and rescue operations in the event of an emergency. For the ELT to function correctly when needed, it must be in the armed position. This means that the device is ready to automatically activate and transmit a distress signal if the aircraft experiences a sudden impact or emergency situation.

Having the toggle switch in the armed position ensures that the ELT can detect a crash or emergency situation and respond accordingly. This setup allows it to broadcast a distress signal on emergency frequencies, enabling search and rescue teams to locate the aircraft quickly. This is essential not only for regulatory compliance but also for the safety of the crew and passengers.

The other scenarios described indicate problems with the ELT setup. For instance, if the switch is in the off position, the ELT will not function when needed. If it is not secured in its holder, it could be damaged or become inoperable during flight. Lastly, if the battery low indicator is active, it suggests the ELT may not have sufficient power to operate effectively, leading to a failure in transmitting signals when required.
