What frequency is used for the En Route Flight Advisory Service (EFAS)?

• A. 118.6 MHz
• B. 122.0 MHz
• C. 126.2 MHz
• D. 128.3 MHz

Answer: (B)

The En Route Flight Advisory Service (EFAS) is commonly known as Flight Watch and is designed to provide pilots with real-time weather information and other advisory services while en route. The designated frequency for EFAS is 122.0 MHz, which allows pilots to communicate with flight service stations to receive updated weather information, airspace updates, and other critical data that may affect their flight. Using this specific frequency enables pilots to maintain situational awareness and make informed decisions during their flight. While there are other common communication frequencies used in aviation, such as 118.6 MHz for ATIS or 126.2 MHz for UNICOM, these options do not provide the same advisory services that EFAS offers, making 122.0 MHz the correct choice for accessing flight advisory services effectively.
