Abstract: A method of extending a landing gear of an aircraft is disclosed. The aircraft includes an uplock arranged to retain the landing gear in a retracted position, a primary landing gear system configured to retract and extend the landing gear, and an alternate landing gear system, independent from the primary landing gear system. The method includes the primary landing gear system holding the landing gear in place while the uplock is moved from a first configuration to a second configuration by the alternate landing gear system.

Abstract: A load-bearing structure is disclosed and configured to, during operation of the structure, transfer load from a first part of the structure to a second part of the structure via a load path. The component includes a matrix material, a plurality of longitudinal first reinforcing elements embedded in the matrix material, and a plurality of longitudinal second reinforcing elements embedded in the matrix material. The long axis of each first reinforcing element is substantially aligned with a first direction and the long axis of each second reinforcing element is substantially aligned with a second direction, the second direction being substantially perpendicular to the first direction. The structure has a predefined crack-propagation region configured to control the propagation of a crack in the structure. The crack-propagation region either comprises multiple first reinforcing elements and does not comprise any second reinforcing elements; or comprises multiple second reinforcing elements and does not comprise any first reinforcing elements.

Abstract: An aircraft access cover for an opening in the surface of an aircraft. The aircraft access cover includes a first panel and a second panel, the first panel and second panel configured to be attachable to each other such that the surface of the aircraft is clampable between the first panel and second panel when the first panel and the second panel are attached to each other. A device that is operable to perform a function while attached to the aircraft access cover is attachable by a connector to the first panel of the aircraft access cover, the connector allowing the device to be movable between a first orientation relative to the first panel and a second orientation relative to the first panel.

Abstract: A method of monitoring a mechanical connection between a first aircraft component and a second aircraft component. The method includes securing, using a securing device, the first aircraft component to the second aircraft component; obtaining information indicative of an acoustic signal emitted during the securing the first aircraft component to the second aircraft component; and inputting the information indicative of the acoustic signal into a machine learning model. The machine learning model is configured to provide an output indicative of a fault condition of the mechanical connection.

Abstract: An aircraft wing section assembly is disclosed having a structural spine, a movement mechanism including a support rod 1 extending through the structural spine, a first lever, for connection to and for moving a first moveable control surface, pivotally mounted to the support rod, a second similar lever for connection to and for moving a second moveable control surface, and a connection mechanism for connecting the first and second levers such that pivotal movement of the first lever causes pivotal movement of the second lever, and an actuation mechanism for actuating pivotal movement of the first lever, such that, in use, when the actuation mechanism actuates pivotal movement of the first lever, the second lever also pivotally moves, thus causing movement of both the first and second moveable control surfaces. Also disclosed is an aircraft wing assembly, an aircraft and a method of operating an aircraft.

Abstract: A tire monitoring device and method in which an error can be detected and indicated. The tire monitoring device includes an indicator and a wireless communication interface. The method of operating the tire monitoring device includes: receiving an instruction to measure a tire pressure via the wireless communication interface; measuring a tire pressure; determining an error status of the tire pressure monitoring device; and responsive to a determination that the error status is not indicative of an error, activating the indicator to provide an indication based on the tire pressure.
