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.

System and method to detect anomalous wingtip extension for a folding wing tip aircraft

A latch pin actuator comprises a primary lock, a spring, and a piston. The primary lock is attached to a primary lock cam and has a notch. The spring is biased to lock the primary lock. The piston is configured to unlock the primary lock.

Monitoring of high-lift systems for aircraft. In one configuration, a method for monitoring a high-lift system includes monitoring a first current draw of a first drive station of the high-lift system, and monitoring a second current draw of a second drive station of the high-lift system. The method further includes comparing the first current draw and the second current draw to determine if a differential between the first current draw and the second current draw exceeds a threshold, and generating a failure signal if the differential between the first current draw and the second current draw exceeds the threshold.

Monitoring of high-lift systems for aircraft

An apparatus comprises a sensor system, a flexible line, and a sensor. The sensor system is capable of detecting skew in at least some of a plurality of control surfaces for a vehicle. The flexible line extends across a number of interfaces for a portion of the plurality of control surfaces. The sensor is connected to the flexible line and is capable of detecting the skew in the portion of the plurality of control surfaces in response to a selected amount of movement of the flexible line.
