'keitei' makes an interesting point in #2335 .

May we put this 'AoA/FPV' etc discussion to bed here please? You can have a 'safe' AoA with a dangerous FPV and vice versa. AoA, as those who have used it know, is a great tool for approach and landing. Trying to 'peg' a value of 'AoA' or an 'FPV' in the middle of a storm area would, I suggest, defeat most 'sky gods'. The more info you put on a display, the more 'chimes/alerts/ECAM messages you insert, the more challenging it is to sort wheat from chaff when it all turns to crock - sensory overload cuts in big time, and I'm sure happened here, and the captain (reportedly) shouting commands at the pilots could have added to the distraction (Q - what is the first 'sense' to be lost under stress?).

The message is clear, if 'old-fashioned' and not 'software driven'. Maintaining the correct pitch and power will generally get you out of trouble, despite temporary 'excursions', even momentary stalls/high-speed excursions, if the weather is really rough. Overall you should get through it. Rely on what may be badly degraded bells and whistles or excessive clever and pretty CRT displayed info and you may well not.
