What action should be taken to ensure the ELT system is ready for emergencies?

• A. Set the switch to OFF
• B. Set the switch to ARM
• C. Leave the switch in the ON position
• D. Activate the transmission settings

Answer: (B)

To ensure the Emergency Locator Transmitter (ELT) system is ready for emergencies, it is essential to set the switch to ARM. When the switch is in the ARM position, the ELT is in standby mode and will automatically activate in the event of a crash or emergency situation, thereby transmitting a distress signal. This functionality is critical as it allows for prompt location and rescue.

Leaving the switch in the OFF position would deactivate the system, preventing it from functioning when needed. Keeping it in the ON position would result in continuous transmission, which is not practical for emergency preparedness and could deplete the battery. Activating transmission settings may imply manual operation, which is not the intended immediate response in an emergency scenario. The ARM position is designed specifically for quick and automatic activation during emergencies, ensuring the system is both ready and efficient.
