Maybe I misread your post then - I interpreted your statement as saying that the Cd alone doesn't determine whether an object is aerodynamic, which is what I was disagreeing with. I do agree fully with your statement here (that the small parachute has a smaller CdA than the 787, but is less aerodynamic).
