What frequencies can be used after departing the airfield listed on fig 22?

The frequencies available for use after departing an airfield typically consist of common aviation communication frequencies, including ground control, departure control, and en-route frequencies. The correct answer includes frequencies that are often used in various phases of flight following takeoff.

For instance, 128.25 and 132.65 are commonly associated with approach and departure control frequencies, which would realistically be utilized after takeoff for effective communication with air traffic control. The frequency 122.0 is commonly designated as a universal unicom frequency used for advisory purposes, making it suitable for general aviation communication.

In contrast, the other options may include frequencies that are either less commonly utilized for departure communications or used primarily for different purposes, such as descent or approach, or may not be frequencies assigned for en-route or departure operations. This aligns with the need for pilots to utilize the appropriate frequencies after departing and ensures that the correct communication channels are used during different phases of flight.
