What is the frequency range for voice transmissions within the Airband?

The frequency range for voice transmissions within the Airband is 118-136.975 MHz. This range is designated for aeronautical radio services and is utilized for various types of communication, including voice transmissions between pilots and air traffic controllers, as well as between pilots themselves. This specific range is crucial for maintaining safe and effective communication in aviation, as it allows for clarity and reliability over distances that can be quite considerable, especially during flights.

Individual channels within this range are assigned to specific services and functions, ensuring that pilots and air traffic controllers can effectively coordinate their activities. The precise allocation of frequencies within this range helps to minimize interference and maximize the efficiency of communication, which is critical for flight safety.

The other frequency ranges provided in the options do not represent the standardized voice communication frequencies used in aviation. For instance, the range of 108-117 MHz is dedicated primarily to navigational aids, such as VOR and ILS systems, rather than for voice communications, whereas the ranges from 120-130 MHz and 126-136 MHz do not encompass the full spectrum allocated for aviation voice transmissions. Thus, the selected answer accurately reflects the standard frequency range used for voice communications in aviation.
