It seems I have lost track of latest TCAS features; please tell me how and on which frequency conflicting aircraft are chatting with each other.
If they really can do so then chaos must be complete because there are still planes around with bare transponders mode C and older type TCAS without chat-function all requiring different treatment by the TCAS computer.
I agree this tratment list is a "nice to know" because the computer has to do the main work when time is a factor but when having this list in hand of YOUR TCAS system it makes you confident it really exists...
If you are using CDG departures to north please reduce your rate of climb when approaching FL 100 because we are flying steady at FL 110 on approach and cannot help in avoiding "nuisance alerts" - I allways do this when I am on departure and you are on the approach.
