Hi.. studying for an oral board during training with NATS...
There are a couple of bits of TCAS knowledge I need to reinforce.
TCAS on one aircraft reads the Mode C of a non-TCAS equipped aircraft and will provide an RA to that aircraft. The other aircraft will buzz along not knowing anything has happened?
TCAS II needs Mode S because of the datalink abilities in order to co-ordinate RA's
TCAS will provide an RA against aircraft with Mode C regardless of their Mode A (e.g. TCAS RA's against A7000/A0000 etc)
Thanks for your time, I'd appreciate if anyone could tell me if I have went wrong anywhere in my studies
