Abstract: A system and method for a number of backup systems in an aircraft. The apparatus comprises a movement system; a latch system; a lock system; and at least one of a backup valve, a backup actuator, or a backup power source connected to at least one of the movement system, the latch system, or the lock system. The movement system has a first number of actuators and is connected to a hydraulic power source. The latch system has a second number of actuators and is connected to the hydraulic power source. The lock system has a third number of actuators and is connected to the hydraulic power source.

Abstract: A wing fold system of a wing of an aircraft. The system may include a first lock of a latch to prevent movement of a latch pin of the latch to prevent movement of an unfixed portion of the wing with respect to a fixed portion of the wing, the first lock may include a first cam configured to prevent the second lock from transitioning to a second engaged position until the first lock may be in a first engaged position via contact with a second cam of the second lock. A second lock of the latch, the second lock may include the second cam configured to prevent the first lock from transitioning away from the first engaged position until the second lock transitions away from the second engaged position.

Abstract: Illustrative embodiments may provide for an apparatus and method of controlling the folding of a wing. The apparatus may include a sensor, an actuator, and a wing fold controller. The method may include receiving a status of at least one of an aircraft and a wing fold system of the aircraft by the wing fold controller of the wing fold system. The method may also include receiving an automated command by the wing fold controller in response to receiving the status. The method may also include operating the wing fold system by the wing fold controller based on the automated command and the status. The method may also include transitioning a wingtip of a wing of the aircraft to one of a flight position and an on-ground position by an actuator of the wing fold system in response to commands from the wing fold controller.

Abstract: A method and apparatus for controlling a movement of a control surface comprises a first linkage system, a second linkage system, and an actuator system. The first linkage system is connected to a first location of a control surface. The second linkage system is connected to a second location of the control surface. The first location is closer to a leading edge of the control surface than the second location. The actuator system is configured to move the first linkage system and the second linkage system.
