Would one of the many people taking the idea of a TCAS
Antenna fault and running with that idea please provide
validation of that interpretation of the reported ACARS line referring to TCAS, i.e.
34 43/06 WRN WN0906010210 344300506 NAV TCAS FAULT 09-06-01 AF 447
Since I've seen a number of statements that this is not an antenna specific fault, and is entirely consistent with a faulty/erroneous/unreliable air data input. (Including one reference to a
QRH procedure)
