exactly in line with the Tu-154 manual
Being a PPL amateur I had the chance 4 years ago to buy a sim hour in the TU5M sim of S7 for peanuts just out of curiousity. The sim then had TCAS but it was not included in any checklist whether it works or not so I asked the pro riding with me about it. His statement was more or less "oh, yes, we have it but if it is u/s we go anyway". This, well noted, on a "better" airline going to the "West" frequently.
Question ímho is therefore - did Bashkirian drivers ever go a REAL trainig in it, ie did they really learn to obey it???
(NOT blaiming them but possibly their company!!!)
