What are the designated emergency frequencies for aircraft communication?

• A. 121.5 VHF and 243.0 UHF
• B. 119.0 VHF and 278.0 UHF
• C. 132.0 VHF and 256.0 UHF
• D. 126.7 VHF and 450.0 UHF

Answer: (A)

The designated emergency frequencies for aircraft communication are indeed 121.5 VHF and 243.0 UHF. These frequencies are recognized globally for distress calls and emergency situations. 121.5 MHz is the VHF frequency primarily used by civilian aircraft for emergency communications and is monitored by air traffic control and other aircraft. This frequency is critical because it allows pilots in distress to communicate their situation and receive assistance. 243.0 MHz, on the other hand, is the UHF emergency frequency utilized by military aircraft. It serves a similar purpose as the VHF frequency, providing a means for military pilots to signal for help during emergencies. Other options present different frequencies that do not serve as global emergency standards. Maintaining knowledge of these emergency frequencies ensures pilots can effectively communicate in critical situations.
