Somehow, you seem to think that I (and others) are attempting to derive advice to pilots. I, on the other hand, thought you were attempting to understand the technical workings of the system. That is, each thought the other shared a goal with him. I no longer think that is the case.
I agree. However, when one of your group(who's profile says accident analyst) goes on a widely read pilot forum and says that doing what the Tupolev crew did was a rational choice, it could easily be interpreted by some readers as advice even if it wasn't meant that way.
Perhaps you should say that you have "discovered or are aware of certain very rare occasions where following a TCAS RA could create a secondary conflict, however, in the vast majority of cases, all pilots following the RA including the 154/757 situation will prevent a collision."
Meanwhile I think some learning of the whole system has been accomplished on this thread about procedures such as when TA is selected and links to safety reports and newsletters and questions asked by others so this has been a useful thread. Glad to have been of help.
