    Abstract: In an aircraft, bi-stable power drive units (PDUs) move and secure cargo within an aircraft cargo hold. Such a PDU includes a frame, by which the PDU is rigidly attached to the cargo hold floor; a body pivotably attached, via a hinge, at a first end of the frame at least one drive roller attached at a second end of the body; and an actuator attached to the body and which causes a pivoting angular movement of the body, relative to the frame, about the hinge. The actuator maintains an angular position of the body relative to the frame even upon a loss of power to the PDU. The body is movable between and including a retracted position and a deployed position. A cargo management system includes a plurality of such PDUs, at least one having a controlled area network (CAN) bus interface to control and communicate with a controller.

    Abstract: In an aircraft, latches are used to secure cargo within the cargo hold of the aircraft. Such latches include a base plate configured for rigid attachment to a surface of the cargo hold, a latch head attached to the base plate and configured to prevent a movement of at least one cargo unit in a Y-direction and a Z-direction and to allow a movement of the at least one cargo unit in an X-direction, and a roller assembly attached to the base plate, opposite the latch head, and comprising at least one roller, the roller being configured to provide a vertical support to the at least one cargo unit in the Z-direction while allowing the movement of the at least one cargo unit in the X-direction.
