    Abstract: A structural health monitoring arrangement comprises a component (panel 30) formed of fibre reinforced composite material with a plurality of electrical conducting fibres (conductors 32) intrinsic to the composite defining electrical paths that run through the composite. The paths act as sensing paths running through the material and a detector watches for changes in electrical property indicative of a structural (8x8 array of LEDs 36) event. The paths may be configured as an open or a closed node grid whose electrical continuity is monitored directly or indirectly. Alternatively they may be fibres having a piezoresi stive property and the changes in resistance may be monitored.

    Abstract: An aircraft undercarriage system comprises a fluid circuit 18, a pump 20 for pumping fluid through the fluid circuit 18, an undercarriage leg 10 which can be raised and/or lowered by means of a first fluid operable jack 12 arranged in the fluid circuit 18, and a shock absorber 24 for the leg 10 which defines a reservoir of fluid 20 for the fluid circuit. The circuit also includes a second fluid operable jack 30 for operating the undercarriage door 28, and the pump operates the two jacks substantially simultaneously or in timed relationship.
