Flight control surface authority question.

  1. May 31, 2013 #1
    Hey everyone,

    I'm trying to figure out what formula I would use to find the authority a flight control surface (not a wing) would have when deflected. I've been searching and searching for information, but if anyone has done some similar calculations, the help would be greatly appreciated!

    Not a simple question, as the industry still encounters problems here, even in fairly mature aircraft.
    For instance, the prototype C130J was lost because of inadequate control authority in a flight test.
    Plus the authority can vary depending on the air flow around the control surfaces.
    So the basic calculations are just a beginning.
