Looming and installation practices are a critical aspect of any aircraft electrical/avionics installation. In order to
provide a reliable and efficient system it is important that the harness installation is designed for reliability and
maintainability. This concept holds true for both copper based and fibre optic harnesses.
The objective of this part of EN 4533 is to provide technical advice and assistance to designers and engineers
on the incorporation of fibre optic harnesses into an airframe, while maintaining maximum compliance with
current aircraft electrical harness procedures. This part considers the looming and installation aspects during
initial design, throughout the manufacture and installation of the fibre optic harness and how the practices
chosen affect through life support of the harness.
