A system is described to control the flight path of a parafoil. The physical control mechanism is a series of actuators embedded within the parafoil canopy that open a series of holes via slits in the upper surface of the parafoil canopy. Opening and closing the holes changes the forces and moments acting on the parafoil canopy in a consistent manner such that it can be used for flight control. The embedded actuator is attached to a structural cell wall of the parafoil canopy. A control line from the actuator extends through a ring attached to the leading edge of the slit in the upper surface of the parafoil canopy and back down to the lower surface of the parafoil canopy along the opposite side non-structural cell wall.
