HF ICAO Aeronautical Frequencies
 

 

Here is a list of HF frequencies used for commercial aircraft operations. When an aircraft is beyond the the range of VHF to communicate with A.T.C they rely much on the use of these HF frequencies. On transoceanic flights VHF is virtually useless unless they're within line of site to the center they wish to communicate with. Aircraft communications heard on the ICAO frequencies are position reports, eta's, weather conditions, and other relevant information regarding the flight or the aircraft.

 

 *HF    = High frequency

 *VHF   = Very high frequency   

 *USB   = Upper side band

 *A.T.C = Air traffic control  

 *ICAO  = International Civil Aviation Organization

 *Eta   = Estimated time of arrival

 

 note: all frequencies are USB mode.
