Abstract: A method to and an apparatus including a processor configured to determine a mass parameter indicative of a mass of an aircraft brake assembly, the mass parameter determined using an estimated amount of energy absorbed by the brake assembly in a given period of time and a corresponding estimated change in temperature of the brake assembly. Also disclosed is a non-transitory computer readable storage medium having stored thereon instructions which when executed by a processor, cause the processor to perform the method.

Abstract: A bulk bin and bag dispensing apparatus comprises a bag fitment having an elongated buttress female thread and a nipple adapted to be joined to the bag fitment. The nipple comprises an elongated body portion having an axial flow passage therethrough and a projection portion extends radially therefrom. The body portion further includes a first end and a second end. The first end is defined by male buttress thread thereto and the second end is defined by NPT thread thereto. The first end includes a ring cutter and at least one sealing means attached thereto so that the nipple strokes threadedly within the elongated buttress female thread causing the ring cutter to puncture a bag membrane to thereby permit liquid to be dispensed through the flow passage.

Abstract: A window for an aircraft door includes an outer pane, an inner pane, and a Fresnel lens element provided in the interspace formed between the inner and outer panes. The Fresnel lens element may be a self-supporting lens element pane positioned intermediately within the interspace between the inner and outer panes, or a lens film adhesively bonded onto the surface of the inner pane facing the interspace, or a Fresnel lens configuration provided directly on the surface of the inner pane facing the interspace. The Fresnel lens element provides an expanded field of view, especially in a downward direction, when looking out through the window, to comply with safety regulations that require visual inspection of the area outside of the aircraft door and especially below the door, before opening the door.
