1. A method comprising: determining whether each of a movement system, a latch system, and a lock system is responsive; andin response to determining one of the movement system, the latch system, or the lock system is not responsive, utilizing at least one of a backup valve, a backup actuator, or a
1. A method comprising: determining whether each of a movement system, a latch system, and a lock system is responsive; andin response to determining one of the movement system, the latch system, or the lock system is not responsive, utilizing at least one of a backup valve, a backup actuator, or a backup power source to perform an operation of a folding wing tip with at least one of the movement system, the latch system, or the lock system. 2. The method of claim 1, wherein in response to determining all of the movement system, the latch system, and the lock system are responsive, performing the operation using a primary power source and a number of primary actuators. 3. The method of claim 2, wherein in performing the operation using the primary power source and the number of primary actuators, the operation is performed without utilizing the backup valve, the backup actuator, or the backup power source. 4. The method of claim 1, wherein utilizing the at least one of the backup valve, the backup actuator, or the backup power source to perform the operation with the at least one of the movement system, the latch system, or the lock system comprises: providing hydraulic power to the at least one of the movement system, the latch system, or the lock system from the backup power source. 5. The method of claim 1, wherein utilizing the at least one of the backup valve, the backup actuator, or the backup power source to perform the operation with the at least one of the movement system, the latch system, or the lock system comprises: providing electric power to the at least one of the movement system, the latch system, or the lock system from the backup power source. 6. A method comprising: sending commands, wherein the commands include a command to a movement system to move a folding wing tip to a first position; andin response to the movement system not responding to the commands, sending a command to utilize at least one of a backup valve, a backup actuator, or a backup power source connected to the movement system in moving the folding wing tip to the first position. 7. The method of claim 6, wherein sending the command to utilize the at least one of the backup valve, the backup actuator, or the backup power source connected to the movement system in moving the folding wing tip to the first position comprises: sending a command to provide hydraulic power to the movement system from the backup power source. 8. The method of claim 6, wherein sending the command to utilize the at least one of the backup valve, the backup actuator, or the backup power source connected to the movement system in moving the folding wing tip to the first position comprises: sending a command to provide electric power to the movement system from the backup power source. 9. An apparatus for movement of a folding wing tip, the apparatus comprising: a movement system having a first number of actuators, the movement system connected to a hydraulic power source;a latch system having a second number of actuators, the latch system connected to the hydraulic power source;a lock system having a third number of actuators, the lock system connected to the hydraulic power source; andat least one of a backup valve, a backup actuator, or a backup power source connected to the movement system. 10. The apparatus of claim 9, wherein the backup actuator is an electric motor connected to the movement system. 11. The apparatus of claim 9, wherein the backup actuator is a hydraulic motor connected to the movement system. 12. The apparatus of claim 9, wherein the movement system is connected to a primary electrohydraulic servo valve, and wherein the backup valve is a backup electrohydraulic servo valve connected to the movement system and connected to the primary electrohydraulic servo valve through a valve. 13. The apparatus of claim 9, wherein the backup actuator is a hydraulic motor connected to the latch system and the lock system. 14. An apparatus for movement of a folding wing tip, the apparatus comprising: a number of actuators connected to at least one of a movement system, a latch system, or a lock system;a hydraulic power source connected to the number of actuators; andat least one of a backup valve, a backup actuator, or a backup power source connected to the movement system, wherein the at least one of the backup valve, the backup actuator, or the backup power source is only used if the at least one of the movement system, the latch system, or the lock system is non-responsive. 15. The apparatus of claim 14, wherein the backup actuator is an electric motor connected to the movement system. 16. The apparatus of claim 14, wherein the backup actuator is a hydraulic motor connected to the movement system. 17. The apparatus of claim 14, wherein the movement system is connected to a primary electrohydraulic servo valve, and wherein the backup valve is a backup electrohydraulic servo valve connected to the movement system and connected to the primary electrohydraulic servo valve through a valve.
