 Re: why do some planes have....

Depends on the airplane. On some you don't actually move the aileron...you move a the servo tab (your "trim tab") and the forces created by that actually move the control surface.

Yea like on 737's...anyone ever take a good real long close look at the rudder of the 727. It just looks complex.
It isn't just a simple one piece rudder like the 757/767.
It has two pieces and can move together as one unit or the bottom half can be used as a rudder I would suspect at higher speeds.
Also I believe that the trailing edge of the rudder has hinges allowing the trailing edge to move about and act like a rudder.
And in addition to all that the rudder has a trim tab on it.
Anyone want to tell me why the 727 rudder is so complex?
Very neat tho....
