1) I referenced a source that said the Presidential aircraft was not compatible with the Russian PRMG ILS system, presumably as part of it's cockpit modernization undertaken in 2009. You state, without reference, that dual systems were on board.
2) You state that witnesses "saw the Tu-154 come out of the F bnk as it was rising over the ravine." If this is the case, again without references, then it shows that the fog at the crash site was worse than the fog at the airport, and the ATC did not lie to the aircraft about visibility and ceiling conditions at the airport.
And I'm sorry, but I showed you three PAR approaches from YouTube. I could have listed a dozen, and they all show a hundred times more calls from ATC than the two "calls" in the transcript. Until proven otherwise, there is no way the aircraft was under PAR control. One call at 4 kilometers and one call at 2 kilometers is not a PAR controlled approach.
And last, did the pilots not know how to read a topo map, and thus were unaware of the terrain surrounding the airport? It is part of the standard approach plates, especially at the point where the aircraft impacted the ground.
“...And last, did the pilots not know how to read a topo map, and thus were unaware of the terrain surrounding the airport? It is part of the standard approach plates, especially at the point where the aircraft impacted the ground.”
Have you even looked at the approach plate? The ravine is not there or even written about.
