ABSTRACT:
An emergency escape slide for a commercial passenger airplane includes a girt bar which connects the slide to the airplane. The girt bar includes a middle portion having a rectangular cross section to which the slide is connected, and cylindrical end fittings which are attached to opposite ends of the middle portion. When the escape slide is armed, the cylindrical end fittings are positioned within floor mounted receptacles which permit the end fittings to rotate. Thus, when the escape slide is deployed, the girt bar is permitted to rotate so that the wide axis of the girt bar remains aligned with the loads generated by the slide deployment. In this manner, the strongest portion of the girt bar is in position to react the loads.
