Just completed a similar scenario in the Sim as part of my last PC. It takes maybe 20min (& I did it on a Classic, where we had to elicit the response of the Sim Instructor acting as Cabin Crew to check the viewers , not applicable on the NG) to do. Certainly not the 2+hr in the holding quoted.
Seems weather was well above minima, bit windy, but didn't sound anything too special. . . I am at a loss to understand this 2+hr holding . . . & what they were waiting for ? ? certainly not RVR/cloudbase . . . so what ?
As to the actual accident, well, if what we know is from Flightradar24 is moderately accurate , if they really climbed in the go around to 2500+ ? flight controls ? /trim? /icing (less so but not impossible) /instruments or disorientation ? . . . . . strange one.
Oh, and the 800 has 6 greens, and a procedure to determine how many you need to be good to go, so, even stranger.
