It is not specified in the book.
An aero-engineer told me it does'nt matter in a wind tunnel. But it sure matters on the full size. I am confused. Any thoughts are appreciated.

If they are showing you variation of CL, or any other non-dimensionalised coefficient, with AR then the effect of wing area is removed and even if the tests were conducted on wings of different physical sizes the results are independent of wing area.
