Hawker Down near AKR

I have AOA, I know how it works, and I was willing to learn something new. What I am telling you, is that monitoring AOA takes a scan, and if you don't look at it, it does nothing for you. If you can't hold airspeed, or hold an ILS, then AOA ain't gonna help.

One issue is that your reference airspeeds can be wrong. Barring an AoA vane failure, AoA is not ever wrong. As you mentioned, the Vref approach has worked just fine for many years so none of us are suggesting that it is a have-to-have, nor are we suggesting this would have saved this crew.

How can my reference speeds be off?

No, but my plane tells me my weight, so I then look up ref speeds by that. If you want to split hairs and say that AOA will be more accurate by a knot, ok then.

So there's no potential for inaccurate weight calculation (which, of course, relies on manual entry of loads to begin with...which assumes that passenger counts, or cargo loads are calculated correctly, or annotated correctly on whatever paperwork used to enter into the aircraft system that calculates its weight), or inaccurate transposition of that calculated info into the bug speeds?

How many potential points of human error are there in that chain of events?

My company has damaged a couple aircraft due to V speeds being off.
