Ian W #926, you may have overlooked the stage that actions only follow understanding (with a few startling exceptions).
My concern with the AD, and your view, is that these assume that the crew have an adequate understanding for ‘the case’.
The dominant cue, or initially the more likely one for this failure appears to be stick force. This is only available to the PF. There is no annunciation.
In order to confirm the specific failure there are a series of ‘ands’ to add to the ‘if then’ sequence, any one of which could divert thoughts to alternative situations and actions.
The better design principle is that all failures should be annunciated, and also provide adequate guidance towards understanding, i.e. AoA Comparator in isolation directs attention to the AoA, but in this instance the problem is trim. Similarly for Alt, Speed, Feel, disagreement, none helps to identify trim except in combination, which is a effortful mental task in a situation where time is critical.
