An aircraft flap system and an associated method are provided to facilitate ground roll breaking without compromising in-flight performance. The aircraft flap system includes a first flap (12) and a panel (14) pivotally attached to the first flap, such as to a rearward portion of the first flap (12). The aircraft flap system also includes an actuator (15) configured to controllably position the panel in a stowed position and in a deployed position. In the stowed position, the panel serves as a continuation of the first flap (12), thereby contributing to the lift provided by the first flap during flight. Conversely, in the deployed position, a panel is articulated relative to the first flap (12), thereby reducing or eliminating the lift otherwise provided by the flap, following landing of the aircraft.
