What frequency range is commonly used for ground control communications?

The frequency range most commonly associated with ground control communications is between 121.6 to 121.9 MHz. This range is primarily designated for communication with ground control at airports, where pilots can relay their intentions, receive taxi instructions, and confirm clearances.

The widely recognized 121.8 MHz frequency is often used as a universal emergency frequency and for announcing intentions at non-towered airports, which ties into the operations related to the choices surrounding ground control. Ground communications require specific frequencies that are carefully allocated among various aviation services, ensuring safe and orderly operations on the airport ground.

Other options provided represent different segments of the aviation VHF band. For instance, frequencies 120.0 to 120.5 MHz are typically used for ATIS (Automatic Terminal Information Service) and other purposes. The frequencies 122.0 to 122.5 MHz are often utilized for non-towered airport communications orUNICOM purposes, while the range from 121.0 to 121.5 MHz is used for various communication needs, but not specifically designated for ground control at airports.

Understanding these frequency usages is vital for pilots to ensure effective communication and operational safety in the airspace system.
