TCAS Fault
Greaybeard:
As mentionned meany times before on this thread, "TCAS inop" is a resulting listed inop system in the ECAM "ADR disagree" STATUS page on the Airbus.
It is so decribed in FCOM Vol3, under the list of ECAM messages which present ECAM checklists/actions AND STATUS page.
IT SO HAPPENS THAT ALL THE ACARS MESSAGES from AF447 ARE CONSISTENT WITH AN ADR DISAGREE MESSAGE.
For the last time !
