Hi Gums,
Just 'cause there isn't an AOA gauge for the pilots doesn't mean that the aircraft doesn't know what value it is. All we need to do is instruct the aircraft properly what to do with the AOA data when it's usual stuff like airspeed starts to drop off the line.
The problem seems to be that the engineers have been thinking in terms of airspeed and not in terms of it's alter ego, AOA.
You know how to fly an aircraft using just AOA and so do I, but for some reason they didn't tell F-GZCP how to do it.
