If a windshear GA,then they would not change config.Once they get that positive shear back,their IAS will increase by a huge amount,and now they have flap overspeed(flaps still at 30),so FD commands increasing ANU.Pilot follows FD religiously at first.Red overspeed bar reinforces this need.This could be 30-40 deg ANU.This sets the trap.
Was he flying HUD or PFD/FD?We've already had it confirmed from HUD pilots that they revert to PFD often.We need more input from HUD pilots.
