Thank you all,
It's very interesting to see all that you know. Concerning the Convair, this question was asked only because my captain has seen the ailerons a little bit up (maybe 1 inch above the trailing edge see from the cockpit). It's not a setting from the maintenace dept or convair manual.
As I ever seen in flight test manuals and reference guides, the answer is depending of what we're talking about.
Thank you for your help.
