An aircraft trailing edge device, coupled with an aircraft wing, provides a reduction in jet-flap interaction noise while preserving the aerodynamic load capacity of the trailing edge. Embodiments of the present invention provide a trailing edge flap device that includes a center flap portion and outer edge portions, where the center flap is shorter in length in comparison to the outer edges. Additionally, the center flap is curved in the planform of the trailing edge device.
