Polish Presidential Flight Crash Thread

Upon examining the schematics, I see it actually might be a correct theory:

The automatic GoAround is initiated with the throttle levers in the position «Взлетный режим» (takeff) or by pressing GoAround with «Уход» button on the yoke.

Obviously, if they tried the throttle levers, it would have worked one way or another, and the FDR would show it – it just would not be the "automatic" goaround – complete no-brainer. So the only question is if perhaps they were sitting there clicking the «Уход» button on the yoke.

Landing modes are set with the buttons “заход” (landing) and “глиссада” (glidepath). These buttons are on the module which also contains all the light indicators of the current flight mode.

This module has "Command TurnOn GoAround " input 24, and a "GoAround Active" output 23. It is most likely that the FDR records that output 23. The logic linking these two things is quite complex, dependant on states of other buttons. I am trying to figure it out for sure, but, I thought I would give you a shot at it. (Your Russian is probably better than mine )

I uploaded the schematic for you.
