The survival radio used in the procedures operates on which frequency?

Survival radios are built to reach rescuers on specific emergency channels. In this context, the airborne survival radio uses a UHF emergency frequency of 243.0 MHz because it’s designated for military aircrew and SAR operations, offering reliable range and direct coordination with rescue assets. The other options serve different systems or roles: 121.5 MHz is a traditional civilian distress channel but is being superseded by newer methods; 406 MHz is for satellite-based beacons, not direct air-to-rescue radio; and 156.8 MHz is marine Channel 16, used for ship-to-ship or ship-to-shore communications. So, 243.0 MHz is the frequency used by the survival radio in these procedures.
