"One means known to the art, and which is most frequently employed, for the control of paragliders is the displacement of the center of gravity thereof with respect to its pressure point or aerodynamic center. Displacement of the center of gravity towards the front or rear of the aircraft results in a change of the angle of incidence whereas a displacement to either side results in a change in the direction of flight." Aircraft having flexible wing surfaces
