But Shirley...
The AOA vanes measure the airflow relative to the fuselage on which they are mounted, not the wing. Is this value displayed unchanged, or is it modified to account for riggers' angle?
And Meikleour's suggestion of using the bird has great merit - it shows you how AOA/Cl varies in different configs and at different speeds, a non-stop aerodynamics lesson in flight instead of the classroom.
