mo32a Posted February 24, 2011 Share Posted February 24, 2011 I'm certainly no electrical engineer, but their explanation of filtering out your own transmission so you can hear an incoming one does not resolve the problem of two aircraft calling at the same time to a listening third party as they state.To my mind you would be able to hear the other aircrafts tx while you were also txing but the third party would hear both transmissions on top of each other, no?

inchman Posted February 24, 2011 Author Share Posted February 24, 2011 Yeah, but you since both transmitting aircraft could hear the other, they would stop transmitting as soon as they heard the other aircraft rather than completing their transmissions and wasting 15 or 20 seconds of air time with everyone else listening to the squeal.And think of the improvement in ACARS speed.... ground stations could hear inbound traffic even while they are transmitting, and VV.

Say Again, Over!

I can just imagine the conversation:- (Both at the same time)ATC: I'm sorry go aheadPilot: No, you started first, you go ahead.ATC: Are you sure? 'cause I can wait.Pilot: No, really, you first... but can we get lower now? Link to comment Share on other sites More sharing options...

mo32a Posted February 25, 2011 Share Posted February 25, 2011 So what's wrong with that? The only thing wrong with it is that it would never happen! Link to comment Share on other sites More sharing options...
