Which frequency should en route weather advisories be obtained from below FL 180?

1. 123.0 MHz

2. 121.5 MHz

3. 126.7 MHz

4. 122.0 MHz

The correct answer is: 122.0 MHz

En route weather advisories can be obtained from the frequency 122.0 MHz. This frequency is specifically designated for common traffic advisory frequency (CTAF) and is widely used by pilots to communicate with each other, especially in uncontrolled airspace. It is important for private pilots to understand that below FL 180, 122.0 MHz is commonly used for obtaining en route weather information, as it allows pilots to receive updates on weather conditions that may affect their flight. Proper communication on this frequency enhances situational awareness and promotes safety during flight operations. The other options are either not designated for en route weather advisories or serve different purposes. For instance, 121.5 MHz is the international emergency frequency, primarily reserved for distress calls and should not be used for obtaining routine weather information. The other frequencies mentioned, like 123.0 MHz and 126.7 MHz, are also not designated specifically for en route weather advisories below FL 180. Understanding the correct frequency to utilize for weather advisories is crucial for effective communication and flight safety.
