A yaw control system and a method of controlling yaw for an aircraft are
provided. The yaw control system includes a first wing set and a second
wing set which are rotatable in opposite directions. Each of the wing
sets includes at least two wings each including a pivotable flap forming
a trailing edge of its respective wing. A flap control assembly controls
the pivotable flaps of the first wing set and of the second wing set such
that when the pivotable flaps of the first wing set are pivoted in a
first direction by a first set angle, the pivotable flaps of the second
wing set are simultaneously pivoted by a second set angle in an opposite
direction, thereby providing yaw control for the aircraft.
