To verify the ELT status during shutdown checks, which frequency should be monitored?

Explanation:
During shutdown checks you want to confirm the ELT is actively transmitting on a frequency that ground observers can hear right away. The 121.5 MHz aviation distress frequency is the one widely monitored by SAR teams and many ground receivers, so listening on 121.5 provides a straightforward confirmation that the ELT is transmitting. The 406 MHz channel is mainly for satellite tracking and isn’t as easily verified by a quick ground check, the 243.0 MHz is a UHF emergency channel used in different contexts and not the standard for a routine preflight check, and 121.95 isn’t a designated distress frequency. So, monitoring 121.5 ensures you can verify the ELT status effectively.
