Abstract: A folding wingtip aircraft includes a wing that includes a primary portion and a wingtip. The folding wingtip aircraft includes a folding wingtip system configured to rotate the wingtip relative to the primary portion. The folding wingtip aircraft also includes a flight control computer. The flight control computer is configured to, in response to a first determination that a wingtip position of the wingtip is not in a folded position when a second determination indicates that a last completed command by the folding wingtip system was a fold command, set error codes for the folding wingtip system. The flight control computer is also configured to change a setting to indicate that the folding wingtip aircraft is grounded based on the error codes.

Abstract: A hydraulic system (e.g., of an aircraft or other vehicle) includes a pump, a pressure line coupled to the pump and configured to distribute pressurized hydraulic fluid, and a return line configured to return hydraulic fluid to a reservoir. The hydraulic system also includes an auxiliary leakage valve coupled to the pressure line, to the return line, and to an actuator. The auxiliary leakage valve is configured to receive a control signal and, based on the control signal, selectively open a restricted fluid path. The restricted fluid path couples the pressure line to the return line to allow a restricted amount of the hydraulic fluid to flow from the pressure line to the return line.

Abstract: A system and method for controlling one or more flaps of a wing of an aircraft include a first flap moveably secured to a first wing of the aircraft. The first flap is moveable between an extended position and a retracted position. First and second actuators are coupled to the first flap. A flap control unit is in communication with the first and second actuators. The flap control unit is configured to operate the first and second actuators to move the first flap between retracted and extended positions, monitor a first electrical signal provided to the first actuator, monitor a second electrical signal provided to the second actuator, and determine that the first and second actuators are synchronized by monitoring the first and second electrical signals.

Abstract: A method includes implementing, via an electronic controller of an aircraft, an extend command received by the electronic controller from a flight control computer to rotate a wingtip of a wing to a flight position. The method includes, in response to a first determination at the electronic controller that rotation of the wingtip stopped before the flight position during implementation of the extend command, sending a first notification signal to the flight control computer from the electronic controller to cause the aircraft to be grounded and to schedule maintenance of the aircraft. The first notification signal includes one or more first error codes. The first notification signal causes the maintenance to include wingtip-to-latch pin drop maintenance responsive to a determination of the electronic controller indicating that a first particular angle of the wingtip relative to a primary portion of the wing is in a latch pin interference range.

Abstract: A system and method of controlling one or more flaps of an aircraft may include receiving first and second sensor signals from respective first and second sensors coupled to respective first and second actuators that are moveably secured to a first flap of a first wing of the aircraft. The first and second sensor signals relate to one or both of the position or the speed of the respective first and second actuators. The system and method may also include comparing the first and second sensor signals to determine a difference between the first and second sensor signals, and adjusting the speed of one or both of the first or second actuators based on the difference between the first and second sensor signals. A system and method may include determining a difference between one or both of speed or position of the first and second flaps, and adjusting the speed of one or both of the first and second flaps based on the difference between one or both of the speed or the position of the first and second flaps.
