Abstract: A load-decoupling attachment system is configured to secure to a primary structure. The load-decoupling attachment system includes one or more baffle tiers. One or more beams are coupled to the one or more baffle tiers. The one or more beams include a fore end and an aft end. A fore end coupling joint is configured to secure the fore end to a first portion of the primary structure. The fore end coupling joint includes a spherical bearing that allows the fore end to rotate in relation to the first portion of the primary structure. An aft end coupling joint is configured to secure the aft end to a second portion of the primary structure. The aft end coupling joint includes a slot that allows the aft end to linearly translate in relation to the second portion of the primary structure.

Abstract: A guide 100 for a wire harness 610 is disclosed. The guide 100 comprises a first surface 120; a second surface 130, at least a second portion 132 of which is parallel to at least a first portion of the first surface 120; a contoured surface 140 between the first surface 120 and the second surface 130; and a plurality of through, circumferentially enclosed openings 170 extending from the first surface 120 to the second surface 130. The contoured surface 140 has a non-linear central axis 141 parallel to at least the first portion 122 of the first surface 120 and to at least the second portion 132 of the second surface 130. Further, the contoured surface 140 has a concave cross-section 142.

Abstract: A method and apparatus for operating an aircraft. An aircraft system comprises a housing, a standby aircraft management system, and a backup power system. The standby aircraft management system is associated with the housing and is configured to provide communications, navigation, and control of a number of aircraft systems needed for safe flight and landing of an aircraft in which the standby aircraft management system is located. The backup power system is configured to supply power to the standby aircraft management system when the power is unavailable from the aircraft.
