In IVAO, radio communications are simulated using IVAO Pilot and ATC software. It is forbidden to use them for any IVAO activities. The use of aeronautic radio transmitters is reserved for real world flights. In the IVAO network, users must not use any real radio transceiver.
#ATC RADIO TRAFFIC SOFTWARE#
The 8.33 kHz spacing channel is mandatory in some countries in upper airspace.Īs the IVAO pilot software interface is compatible with 8.33kHz, please add the letter Y to the equipment in your flight plan. In your cockpit, you must setup only the first 2 digits after the decimal and the 3rd digit is automatically tuned by the system to either a 0 or 5. The new 8.33 kHz channel width for radio communication frequency is already integrated in the Pilot client and ATC client and the IVAO network servers. Only 8.33 receivers tuned on 118.005 will be able to hear you. Now, if you select 118.005 it will operate in 8.33 mode. If you select on your 8.33 radio frequency 118.000, it will automatically operate as an old 25KHz radio. You may have noticed that frequencies 118.000 and 118.005 use the same real frequency but with a different spacing. Therefore, with 8.33KHz spacing within each channel it gives the following table : Diplayed frequency Hence, within each 25KHz channel we can have three 8.33KHz channels (25/3=8.33).
The solution was to reduce channel spacing from 25MHz to 8.33MHz. Also it was impossible to assign higher channels, as they are used for satellite communications and military operations. It was impossible to assign lower channels, as VOR & ILS uses frequencies from 108.00 to 117.95 MHz. With traffic increasing, it was necessary to create more channels. The aviation VHF communication band ranges from 118.000 MHz to 136.995 MHz. Military aircraft can use the ultra high frequency band (UHF). On oceanic flight, with the long distance involved between ATC and pilots, the High frequency (HF) communication band is selected by using the long range communication property of this frequency.Įxample of a VHF/HF communication panel in a 737 aircraft: In the real world, the pilot uses mainly radio communication in the very high frequency band (VHF) in order to use voice communication. The frequency band definition: Frequency band
The term may refer to a radio band or an interval of some other spectrum. The radio spectrum of frequencies is divided into bands with conventional names designated by the International Telecommunications Union (ITU): A frequency band is an interval in the frequency domain, delimited by a lower frequency and an upper frequency. In half-duplex communication, each party can communicate to the other, but not simultaneously the communication has one direction at a time : ATC to pilot(s), or Pilot to ATC. The radio transmitter can be tuned to the selected frequency manually by its user. In real aviation, all aircraft and all air traffic controllers are equipped with radio transmitters and antennas.Įach radio transmitter uses one unique frequency at a time and performs half duplex communication (this frequency is sometimes also called a radio channel). An air traffic controller shall communicate with pilots in command of all aircraft in his airspace.
