Vilas,
No, it's too soon after release for the sim OEMs to get to grips with it I suspect. We were looking to upgrade the A330 about now but Airbus have deferred this AP/TCAS feature until at least March 2015 and the next release (after 2.5.X I assume).
Are there any tangible differences between 1.7.1 and 1.8 for training?
