The flight controls follow the right hand rule relative to the body axis system. This means that *both* ailerons are positive trailing edge down and negative trailing edge up. > Assume the plane flying steadily now, > if aileron left-up and right-down , that is aileron position increase , the plane >would roll anti-clockwise, that is roll rate (or roll angle) would decrease?
