An aircraft has wing area of 30m and mean aerodynamic chord of 3m. The AC is 1/4 forward of the flexural centre. The lift-curve slope is 3.5. The air density is 1.226 kg/m. The torsional stiffness is 1.92 x 106 Nm. The rate of change of lift coefficient with aileron angle is 0.8 and the rate of change of pitching moment coefficient with aileron angle is -0.25. What is the aileron efficiency?
