Question
Justify the use of the various communication systems used on an aircraft?
Hello,
Typically, the communications system on a Transport Aircraft is as follows:
VHF1 = Used for ATC communications
VHF2 = Used for all NON-ATC communications, and Emergency frequency monitoring.
VHF3 = Typically used for Data transmissions (ACARS)
All VHF can be used interchangably for any VHF purposes.
HF1 = Typically used for Long-Range ATC communications
HF2 = Back up to HF1. (frequently used to listen to the BBC to overcome boredom on longer flights)
SATCOM = Satellite communications to a land based telephone system.
ACARS = Aeronautic Communications and Reporting System. (Data and Text based system for weather retrieval, communications and flight data)
SSR = Secondary Surveillance radar. System that communicates with ATC radar to provide position, speed and altitude information.
TCAS = System that communicates with other suitably equipt aircraft to provide separation against collision.
I hope this answers your question.
Cheers
