We can assume that AoA is the difference between the attitude and the Flight Path Angle (FPA). To be more accurate, we would have to know the rigger’s angle of incidence for the wing.
On a typical approach, attitude is about 2 or 3 degrees and FPA is -3 degrees, so AoA is about 5 or 6 degrees.
During the flare, attitude will increase to about 4 or 5 degrees as the FPA reduces towards zero at touchdown, so AoA will be pretty much the same as it was during the approach.
