====== AIR Band or VHF aeronautical communications band =====
After the Second World War, [[aeronautical communication]] was transferred from the shortwave to the VHF range. It is the only radio service that uses [[amplitude modulation]] in this band.

For radiotelephony, the frequency range 118 - 137 MHz is used, originally in the 50 kHz, then in the 25 kHz and today in the 8.33 kHz channel spacing, so that the number of available frequencies could be multiplied.

The 108 - 118 MHz range is used by radio beacons, the VOR (VHF Omnidirectional Radio Range) beacons; the glide path transmitters for instrument-controlled landing approaches operate in the UHF range of 328 - 335 MHz.
