Airband Frequencies List - OneSDR

Airband frequencies are used for communication between aircraft and ground stations, including air traffic control (ATC), airports, and other aircraft. These frequencies are essential for ensuring safe and efficient air travel.

The airband typically ranges from 108 MHz to 137 MHz, covering VHF navigation and communication channels. Below is a comprehensive list of commonly used airband frequencies and their purposes.

Airband Frequency Ranges

VHF Navigation (VOR, ILS, Marker Beacons)

108.00 – 117.95 MHz: Used for navigation aids such as VOR (VHF Omnidirectional Range) and ILS (Instrument Landing System).

VHF Communication

118.00 – 136.975 MHz: Dedicated to air-to-ground and air-to-air communication.

Programming Airband Frequencies

To use these frequencies effectively in a scanner or aviation radio:

Select the appropriate band: Ensure your radio is capable of receiving VHF airband frequencies.
Input the frequency: Manually enter the desired frequency or use software for programming multiple frequencies.
Monitor the channels: Tune in to different frequencies to listen to air traffic communications and gain insight into aviation operations.

Legal Considerations

Listening to airband frequencies is generally legal and encouraged for aviation enthusiasts and professionals. However, transmitting on these frequencies without proper authorization is strictly prohibited and can result in severe penalties. Always ensure you comply with local regulations regarding radio communications.
