What is the frequency range of aircraft VHF communications?

Explanation:
Aircraft VHF communications use the VHF airband, which is allocated from 118.000 MHz up to 136.975 MHz. This range is specifically set aside for aeronautical voice communications between pilots and controllers (and among aircraft) and is chosen because VHF signals work well with line-of-sight communication at typical aviation altitudes. Some regional allocations note extensions up to about 151.975 MHz, but the standard airband used for routine air‑to‑ground voice is 118.000 to 136.975 MHz. The other ranges are for different purposes: 108.00 to 117.95 MHz is reserved for navigation aids like VOR and ILS, not for voice communications; 329.15 to 335.00 MHz is a UHF band used for other aviation or military purposes, not the primary aircraft voice airband; and 2.000 to 29.999 MHz is the HF band used for long-range communications, not the standard aircraft VHF airband.
