Fly Aiprt,
we debate the same issues, but from differing viewpoints.
Your disagreements about alerts, colour, etc, would have to be compared with existing certification requirements or changed via a time consuming alternative means of compliance.
Re …
must not reason in terms of “we have always done it that way”
Yet, many of the 737 Max MCAS problems stem from alternative reasoning; attempting to mimic a modern protected flight control system in an old aircraft design.
Similarly applying modern training assumptions and technique to an aircraft which did not have sufficient similarity to precious versions.
“
Presenting AOA indication at a useful place is viewed as an improvement. If pilots disagree, they are free to not include it in their scan.”
I strongly disagree on both counts; the ‘ignore’ view promotes a cluttered display. Having to disregard an ‘irrelevant’ display feature is as mentally demanding as looking at and understanding an indication.
