Tcas
Hi,
I have been watching a series of documentaries on one of the Discovery type channels on Sky, about aircraft collisions, and the tragic incident in which a DHL transport and russian airliner collided in 2002 was the subject of the most recent one. TCAS was mentioned many times and I was wondering how the system knows whether to instruct a climb or descent. I have googled, but only manage to come up with links to manufacturers sites, with no detail on how it works.
Thanks in advance
