Effects on Pitching Moment

This plot is found in "Effect of High-Fidelity Ice Accretion Simulations on the Performance of a Full-Scale Airfoil Model", Broeren, Bragg, et.al., 2008
Pitching Moment
This plot shows the angle of attack on the bottom axis, the coefficient of lift on the left axis, and the pitching moment coefficient on the right axis. The lift profile is shown in the upper curves, and the pitching moment is shown in the lower curves.

Note: the pitching moment shown here is of the airfoil only, which is a part of the whole aircraft pitching moment.

Look at the area within the red box.

Will you notice any change in stability? Will you notice any change at all?

Will your autopilot notice any change in stability?
