For nearly every wing aerofoil section the AoA on the Co-efficient of Lift Curve varies from about 4 degrees at cruise speed, and about 7 degrees at approach speeds, to 13 degrees at the stall.
Most small GA aircraft try to flair before landing, to land at the stall speed ( AoA = 13 deg.).
However larger aircraft do not often take it as far as the stall, as if overdone could cause a tail-strike. So they land positively at slightly higher than stall speed, with the AoA in the region of 8 to 10 degrees, and rely upon lift-dumpers to stop the excess energy being translated into a bounce.
