I am just wondering if the TCAS would not have gone off on the SIA plane(assuming it is equipped). MH772 would have to follow pretty close to not be picked up as an individual contact. Does anyone know if TCAS picks up radar contacts, or does it only pick up transponder equipped aircraft.
For TCAS to work as described, both planes would need their transponders set to at least the TA setting. If MH370's transponder was turned off, neither plane would have seen each other.
