- at 100m both PIC and F/O call for GA, the Nav says "all within normal range" (that means altitude, distance, course, etc.) which also means reaching the MM. But they are over 2k from the RWY
I assume that you know that at 100m they should be 2km from the runway if performing a CDA.
You would also then know that the approach allows descent to 100m prior to the missed approach point. The two do not have to coincide.
- during the approach there were problems with navigation, the info from ATC was off, middle marker signal was off, I suspect there was also a problem with the GPS signal - as a result they had a reason to believe they were 1k closer to the RWY than they really were.
now something strange is happening, despite the GA call the plane continues to descend rapidly. Normally you would say that there was no intention to land - they would have turned off the AP. But the plane is not following the straight line. Despite the AP engaged and no one touching the control column the trajectory is gradually changing. There is still the open question about the automatic GA, if it was supposed to work or not. But the behaviour of the crew is strange - the Nav is counting down to virtually 0, no one says anything, the plane gets below RWY elevation. I can only assume some temporary malfunction that makes the plane impossible to control.
How about loss of situational awareness?
Your first "scenario" is entirely possible. It does NOT, however, require any "altered flight data".
The first part of your second scenario is also entirely possible. Again, it does NOT require altered flight data!
At the minima, it is a requirement to see THE RUNWAY on the type of approach being conducted. Searchlights are not a runway, and look nothing like a runway. It is entirely possible they got confused by them, and indeed they may have contributed to the crash. But they are not deliberately or maliciously placed.
Its time you stopped looking through your conspiracy glasses and realised that while you're getting very close to the method of accident itself, you're obsession with blaming somebody is preventing you from seeing it.
