TCAS was only mandated in the USA in 1993
Bloggs,
Check you history books.
All QF, and many Ansett and Australian Airlines aircraft were fitted with early models of TCAS long before it was mandated anywhere. An AATA policy decision, because of the high rate of ATC error in Australia. The now long gone B747 "Classics" had the VSI needle presentation, a retrofit. Every glass cockpit aircraft that I have flown has the RA command on the FDH/ADI/ EADI/name of choice command bars.
All QF B767/744 came factory fitted with TCAS ---- and that is a long time ago, check the delivery dates. Check the date of "Revison 7", which was just about the definitive TCAS 11
Seems to me that you could update quite a lot of your "knowledge" --
and get your facts straight ---before you start criticizing the knowledge of others.
Tootle pip!!
The oldest B767-338 in the QF fleet is about 20+ years old, the now disposed of B767-238 several years older, at least, so there is your 20+ years.
Delivery date: 20/10/1988 for
VH-OGB, as quoted on another web site, so the first seven B767-238 were delivered well before that, starting some time in 1985, starting with VH-EAL, then -EAJ and on.
