Chucks, I was reading your comment where you ask, who trims down during goaround and why.
You have to realize, that the power has a huge influence on pitch.
I think what happened is quite simple. 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. Next think you are leveling out very rapidly, because you had set up your goaround altitude low or started the goaround from an intermediate altitude. Than you need to power back a lot. You are trimmed for nose down due to trying to keep the pitch at 15 with a lot of power and all of a sudden your nose dips down due to power coming rapidly off in order to level out. Add to it the chronique inability of airline pilots to scan instruments coupled with tiredness, somatographic illusion and being behind the aircraft due to a lack of training as was mentioned in previous post.
I think we will see many of such accidents in the future. With the lack of training airline pilots are becoming like a sheep with no survival instincts. They cannot think one step ahead of the aircraft. Everything is a surprise to them.
And doing the 2 previous goarounds fine, while on autopilot and the last one badly because of manual flying... what is so difficult to understand it went wrong? High energy goaround keeps killing pilots with lack of instrument scanning ability, period.
