The designated frequency for Ground Control (GC) operations at airports, including O'Hare, is 121.75 MHz. This frequency is specifically assigned for ground communications and is used by pilots and ground control to coordinate movements on the taxiways and runways. It ensures that there is a clear channel for communication, which is crucial for maintaining safety and efficiency on the airport's ground operations.

Understanding the importance of this frequency is vital for proper operations and coordination at the airport. Pilots must communicate with Ground Control to receive taxi instructions, report vehicle movements, and ensure they are following any relevant air traffic rules while on the taxiways. Overall, using the designated frequency helps promote a safe and orderly flow of traffic on the ground around the airport.
