A refuelling system is disclosed having a fuel conduit, a variable-position valve for controlling a rate of flow of fuel leaving the conduit, and a controller. The controller is configured to receive from a sensor arrangement a measurement of an electrostatic condition in a fuel tank being fuelled by the system. The controller is configured to control the variable-position valve to control the rate of flow of fuel based at least in part on the measurement received from the sensor arrangement.

Refuelling system

A method and device is disclosed for measuring one or more physical properties of, and/or induced by, out-gassing products released from and/or trapped within a joint in response to a lightning strike or other electrical current threat. A device for measuring one or more physical properties of, and/or induced by, gases, plasma and/or particles released from a joint in response to an electrical current threat. The joint includes a fastener passing through a structure so that an end of the fastener protrudes from the structure. The device includes a containment member having a base surrounding an opening into a cavity, the containment member being arranged to be mounted over the end of the fastener to enclose the end of the fastener within the cavity and to seal the opening; and one or more sensors arranged to measure physical properties of gases, plasma and/or particles contained by the cavity.

Methods, device and apparatus for evaluating electrical current threat effects at joints

A joint on an aircraft, the joint comprising: a first component; a second component joined to the first component; and a bonding lead which forms an electrical connection between the components with a resistance between 100 k&#x3a9; and 10 M&#x3a9;. Surprisingly, it has been found that a bonding lead with a relatively high resistance can be used without seriously compromising the static discharge performance of the bonding lead, and that the resulting comparatively low flow of current reduces the risk of sparking in the event of an lightning strike. Bonding leads may be provided as a kit of parts in which at least two of the bonding leads have different lengths and the longer lead is formed from a material having a higher bulk conductivity than the shorter lead. Thus the bonding leads can be made with approximately similar resistances regardless of their lengths.
