Which frequency is designated for outbound communication from CDF of GDC?

The frequency designated for outbound communication from the Chicago Department of Aviation Flight Operations (CDF) of the Ground Control (GDC) is 130.750. This frequency is specifically allocated for this purpose to facilitate clear and effective communication during operations, ensuring that ground personnel can coordinate movements without interference.

Choosing the correct frequency for communication is critical in airport operations to maintain safety and efficiency. Frequencies are assigned for specific types of communication, and using the correct one helps to avoid confusion and ensures that messages reach the intended recipients.

The other frequencies mentioned are likely assigned for different purposes within the airport's communication system, such as approach, departure, or other ground control functions, which means they wouldn't serve the outbound communication from CDF of GDC effectively. It's crucial for operators and personnel to be familiar with the designated frequencies to comply with regulations and ensure smooth airport operations.
