-	Vast areas of the world lack the necessary [[VHF / UHF Radio\|VHF]] [[VHF airband\|airband]] communication [[VHF_airband#Long_Range_VHF_Networks\|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. Each set of frequencies are often referred to as 'families'. Aircraft flying over the major ocean routes often use a combination of HF SSB voice radio, SATVOICE, the ACARS datalink system to communicate with air traffic control and regular VHF aircraft radio to communicate with other aircraft flying at high altitudes. Over the Atlantic and Pacific, the most common frequency for air to air (or "interplane") communications is the so-called "fingers" frequency 123.45 MHz AM. 123.45MHz is designated Pacific Air-to-Air as well as Atlantic Air-to-Air.	+	Vast areas of the world lack the necessary [[VHF / UHF Radio\|VHF]] [[VHF airband\|airband]] communication [[VHF_airband#Long_Range_VHF_Networks\|systems]] needed to provide reliable radio coverage between aircrews and air traffic controllers.
