Major World Air Route Area (MWARA) Frequencies

See: list of MF and HF aeronautical band HF aircraft bands

Vast areas of the world lack the necessary VHF airband communication systems needed to provide reliable radio coverage between aircrews and air traffic controllers. This lack of VHF coverage is generally due to their remote locations - for example much of the airspace over the Atlantic and Pacific oceans. To compensate for this lack of VHF coverage a group of HF Frequencies has been allocated as detailed by the following maps.
