A concept employed in the civil engineering field is that of serviceability. At its core, a structure should only remain in-service as long as it is serviceable. A serviceability limit should be based on measurable performance criterion that, if exceeded, remove it from service. In limit state design, the structure fails its serviceability if the criteria of the serviceability limit state are not met during the service life with the required reliability.
This idea of serviceability is applicable to other engineering disciplines and is undoubtedly applicable to aerospace vehicles. From our perspective at Lectromec, understanding the serviceability of aircraft wiring is critical. However, to determine an aircraft wiring system serviceability state requires the limit state to be defined and assessed. Here we propose three such properties of a serviceable aircraft wiring system.
