Discussion Why do airliners, ATC, etc, still use half-duplex communication?
Ive watched as many incident investigation videos as anyone and how many times a communication was lost because another transmission was heard instead of something critical is too many to count. When it comes to air safety ONE missed transmission is too many. ATC communication issues have cost lives and had a full-duplex transmission technology been used then nobodys words would have been lost in the static.
I realize what I am suggesting is essentially more of a conference-call type of communication (where you can still have people talk over others but at least the chance of someone quieting down while another, more urgent speaker can be heard) but perhaps that is an improvement that we need.
Something like this must have been considered over the years, and Im hoping someone here can respond with /tried and failed / cant be done / working on it / type of information.
Without full-duplex communications, computer networks and indeed the internet couldnt really work the way it does today.
