TCAS
In light of the recent JAL vs. JAL near-miss; I have some questions. I am not an aviation professional- so please humor me.
How does TCAS work from a technical standpoint?
How far apart will it work?
Assuming no confusion or other factors, ATC weather, etc.- with a nose to nose cruising speed and angle- how much warning in seconds can a crew expect?
Thanks in advance to all you professionals?
Fly Safe.
