Would anyone know if the HUD is used during the go round? I've seen them in the sim, but have no idea how it is used.
I have a feeling that if the HUD was used for the missed approach, then the attention of the PF is focused away from the PFD and toward the visual cues outside. This is fine for a low vis landing, but climbing at night into the overcast with the landing lights shining into the cloud, this would be most disorientating.
If the aircraft is accelerating, pitching up and climbing into cloud at night, then I would imagine that the PF would find it very difficult to focus on the pitch attitude unless he concentrated hard on the PFD. It is hard to explain why the previous go round went to plan, but the second went badly wrong, the only difference possibly being that the first go round was due to windshear and the FD pitch commands were followed, but on the second go round, the PF was distracted.
