What is the VHF GUARD frequency in the T-6 aircraft?

The VHF GUARD frequency in the T-6 aircraft is 121.50 MHz. This frequency is designated for emergency communications and is monitored by air traffic control and various aircraft. It serves as a distress frequency that pilots can use to broadcast urgent calls in situations where they require immediate assistance. By using this frequency, pilots can ensure they are utilizing a globally recognized channel for emergencies, which can facilitate quicker responses in critical situations.

The other frequencies listed do not serve the same purpose. For example, 118.00 MHz is commonly used for air traffic control communications, while other frequencies might be assigned for specific operational communications rather than emergency use. Understanding the significance of the VHF GUARD frequency is crucial for pilot readiness and safety during flight operations.
