Abstract: In one aspect, an apparatus for use in forming a kinematic coupling having at least one component including a plate adapted for carrying a plurality of bearing elements comprises a template including a plurality of supports adapted for engaging and assisting in aligning the plurality of bearing elements relative to the plate of the component. The template may be used in forming either a top or base of the kinematic coupling. The top may further be adapted to be inverted relative to the base, which may also include bearing elements for receiving bearing elements associated with the top. Related methods are also disclosed.

Abstract: A computer implemented method, apparatus, and computer program product for managing aircraft software parts. A connection is established between a portable data processing system and a source through a ground network. Uplink commands are retrieved from the source through the established connection. Aircraft software parts corresponding to the uplink commands are retrieved from the source through the established connection. The retrieved aircraft software parts are stored in a portable data processing system. The portable data processing system is disconnected from the ground network. The portable data processing system is connected to an aircraft network in an aircraft. An uplink command is issued from the uplink commands to the aircraft network through an on ground component in the portable data processing system. A stored aircraft software part corresponding to the uplink command is sent to the aircraft network through the on ground component.
