They added a lot of power during the goaround. It is normal and expected. Than the nose goes up a lot during the power application. So you have to push a lot to keep the nose at 15 degrees or to get it down to this 15 degrees, in case you slept through it
Can we please stop repeating this rubbish?
A normal two engine go around in the NG is not a violent, lots of power event. There is no need to push a lot or trim forward go get the nose to 15 degrees. It pretty much parks there if everything works OK.
If, for whatever reason they decided to use full thrust during go around in a light NG, it could get interesting really fast.
This was a single channel automatic approach with a manual go around. The autopilot disconnected just at it should do. FZ SOP.
OKC is a very experienced pilot. Stop making him look like an idiot because he did a typo. He made a post about trying to replicate this crash, but unless I am mistaken, the video posted is not his.
But, what is most puzzling is why the half way down the descent, the flight path steepened still further. Any attempt to pull back on the stick would have resulted in, at worst, a pitch up, however slight and whatever the trim. Perhaps there is a point at which the elevator becomes stalled and looses all effectiveness
The stabilizer is the boss. No way the elevators will bring the aircraft out of a pitch up/down if the stab is grossly out of trim.
