True, Brian,
...but anyone who is looking at an AoA near Vne should not be
flying! there is an argument for the use of AoA at critical speeds such as
endurance, range, and stall, and during manoeuvres, but Vne isn't one of
them! In fact it's one of the very few which call for an airspeed to be
calculated.
Happy Landings
