CPC classification number: B64D9/003

Abstract: A cargo restraint that accommodates restraining ULDs having a distorted or elevated retention base is disclosed (e.g., a retention base that is spaced above a conveyor plane, for instance coinciding with a cargo deck). An outer pawl includes at least one pivot that is maintained in a fixed location on the outer pawl, and that is movable along a slot to change the elevation of the pivot (and the elevation of a restraining head of the outer pawl when in an erected position). Movement of the pivot along the slot first allows the restraining head of the outer pawl to be positioned above a retention base of a ULD, including when the retention base is at an elevated position. Further movement of the pivot along the slot allows the restraining head of the outer pawl to engage and move the retention base of the ULD toward/to the conveyor plane.

Abstract: The disclosure addresses an external lighting unit for an aircraft. This external lighting unit includes a lighting unit housing have a mounting flange that is configured to provide a reduced contact with a supporting structure (e.g., a tail cone of an aircraft), which in turn reduces conductive heat transfer between the supporting structure and the lighting unit housing (more specifically reduces conductive heat transfer between the supporting structure and a printed circuit board that is disposed within the lighting unit housing and that may be seated on a portion of the lighting unit housing). Open spaces on the surface of the mounting flange that face toward the supporting structure may be occupied by a thermal insulator.
