I'll have to go back to my systems books, but Dave has something - my experience in two planes was with a HUD and its pitch and roll display was also related to local level and such. So the inertial vector and my "attitude" were using the same coord frame. My main idea was mainly using pitch, as the flight path marker .disagreed with the aircraft longitudinal reference point on the HUD unless you were at zero gee ( well, mostly).
EDIT: Upon reflection, I ignored wind. So my official position is we can use the inertial velocity vector in low wind or at high CAS to get a crude idea of our AoA but we will need something else besides that string I taped on the side window, heh heh.
Oh well, I honestly tink we can generate a useable AoA without the vanes or cones.
