Penggunaan Dan Manajemen Kanal High Frequency (HF) Pada Sistem Komunikasi Penerbangan Di Bandara Soekarno Hatta

Abstract

In aviation communication systems, especially in voice communication system, there are several types of channels used namely High Frequency (HF) and Verry High Frequency (VHF). The distance that can be reached by HF is wider than VHF, but for sound quality, VHF is better than HF. The use of HF can also be influenced by weather factors. Therefore, the use of HF is not intended for ATC (Air Traffic  Controller), but to the FIC (Flight Information Center). Because FIC does not have the task of giving orders to pilots, the FIC is only in charge of providing information about airspace or routes that will be traveled by passengers. There are several frequencies on each radio usage unit HF radio (RDARA and MWARA). One frequency cannot be used continuously because HF can be affected by weather factors. Therefore, frequency management is a way to determine which frequencies can be used at any given time.
