Safety_Helmut: I'm not saying it's right, I'm just saying that's how I expect the TCAS thing will pan out.
Regarding the 'other TCAS aircraft at risk' comment, we obviously have an IFF with 3/C, so as long as that's working, TCAS-fitted aircraft should see us on surveillance and be able to issue both TA and RAs, with the only caveat that an RA won't have been pre-deconflicted with our own avoiding action.
Again, I'm not saying the status quo is perfect but I don't want people to read this site and think that the situation is worse than it really is.
