Abstract:

A method of assessing potential conditions affecting aircraft electrical wiring systems. Electrical wiring system components potentially affected by a potential failure condition of the aircraft are identified. Probabilistic and/or statistical methods are used to determine exposure of one or more wire segments of the identified component(s) to hazard and whether the exposure meets a predetermined safety threshold. Effects of potential failure modes of the identified segment(s) on a system safety assessment for the electrical wiring systems are evaluated. This method can be used to facilitate compliance with aircraft safety regulations.
