(2) Size of the conduit The choice of size of the conduit depends on the bundle diameter and on the conduit length.
-Convoluted, screened and closed conduits must only be partially filled in such a way that the external diameter of the cable bundle represents: For conduits with a length lower than 2 m (6.56 ft.): Filling rate must not exceed 80% of the conduit section at the time of aircraft delivery (20% of the section spare space available for the customer). For conduits with a length greater than 2 m (6.56 ft.): Filling rate must not exceed 60% of the conduit section at the time of aircraft delivery (20% of the section spare space available for the customer).
