What is the frequency used for the CDF GC inbound communication?

The frequency used for the CDF GC (Ground Control Flight) inbound communication is 131.050. This frequency is specifically designated for coordination and communication related to ground traffic and activities at O'Hare Airport.

Ground Control Frequencies like 131.050 play a crucial role in managing aircraft movements on the ground, including taxiing, holding, and any other ground operations, ensuring safety and efficiency in busy airport environments. Understanding and utilizing the correct frequency is vital for pilots and ground crew to maintain organized communication, which helps prevent incidents and improves overall airport operations.

Other frequencies listed, like 130.750, 121.90, and 121.75, are typically used for different types of communications, such as other ATC interactions or emergency situations, but they are not designated for CDF GC inbound communication specifically. Hence, 131.050 is the correct choice for these operations.
