An accessory system includes an accessory gearbox which includes a geartrain and a 2-Pole generator integrally mounted with the accessory gearbox such that a drive gear of the generator is in meshing engagement with the geartrain, containing a shear section, disconnect mechanism, and torsional compliance. A Multi Top-level Graphical-Container Simulator can be provided to simulate multi top-level graphical container support for applications that expect to use a plurality of top-level graphical containers. The model is then iteratively solved using the computer processor until it has converged to a feasible solution. The tip slide mechanism provides fore and aft movement of the seat assembly along a second curved path transverse to the first linear path between a seating position and an easy entry position to provide access behind the seat assembly. The coiled portion of the spring is rotatably supported by a support member extending from the plate.
