Which frequency is the Emergency Air to Ground frequency?

• A. 118.00 MHz
• B. 126.70 MHz
• C. 121.50 MHz
• D. 123.45 MHz

Answer: (C)

The important idea is recognizing the dedicated emergency air-to-ground channel. In aviation, 121.5 MHz is the international distress frequency used for emergency calls and for pilots to contact nearby air traffic services or search-and-rescue when they’re in trouble or have a radio failure. It’s specifically designated for emergencies and is widely monitored, which helps ensure a quick response. The other options are ordinary aviation frequencies used for routine communications with controllers or airports, not the universal emergency channel. They may be used for standard coordination but aren’t reserved for distress, so they aren’t the correct emergency frequency. That’s why 121.5 MHz is the correct choice.
