CJ@#1314: To me, the suggestion of adding an 'unfamiliar, new' instrument (requiring additional training, too) because, once upon a time, people were incapable of inferring the state of their aircraft from the available data, makes no sense.
Why not to present this (important) info when AoA nears safe limits? Could be triggered by "rate". Warning a fast closing in to a dangerous condition. Requiring immediate action.
Certainly not relevant (and not justifiable) in normal conditions.
Another indicator IMHO should be Real Time info on near simultaneous "failure" of critical (redundant) elements, e.g. Pitot's.
The redundancy implemented in the design was not made to simultaneous failure of it. And the crew should be IMMEDIATELY informed of this unusual condition even before a/c degradation.
Why not? Cost is not an issue. Just a simple SW algorithm.
AFAIK we are still relying in "sub heated" Pitot 's.
