Aeronautical articulation advice is aswell conducted in added abundance bands, including digital articulation on Inmarsat and top abundance articulation in the North Atlantic and limited areas. Military aircraft aswell use a committed UHF-AM bandage from 220.0-399.95 MHz for air-to-air and air-to-ground, including air cartage ascendancy communication. This bandage has a appointed emergency and bouncer approach of 243.0 MHz.28
Some types of navaids, such as Non-directional beacons and Distance Measuring Equipment, do not accomplish on these frequencies; in the case of NDBs the Low abundance and Medium abundance bands are acclimated amid 190–415 kHz and 510–535 kHz. The ILS coast aisle operates in the UHF abundance ambit of 329.3 to 335.0 MHz and DME aswell operates in the UHF band.3
