A routing list (commonly called an ‘RL’) for an aircraft is a list of each wire in a wiring harness. Routing Lists are used on all aircraft including F-16, F-22, F-35, V-22, UH-60, CH-53K, etc. It is called ‘routing’ because it contains the endpoints of each wire. For example, wire NAV-121-22 may go from reference designator P3320 to reference designator J3321. Thus it is ‘routed’ from P3320 to J3321.
Besides listing wire numbers and reference designators, routing lists also contain much more information. Depending on the aircraft company, such as Lockheed Martin, Boeing, Rockwell Collins, Bombardier, or Dassault Systemes, that information typically includes: (1) wire length, (2) wire gauge, (3) contact cavity that the wire is terminated into for both reference designators, (4) how the wire is terminated (such as a contact part number), (5) wire part number, (6) system number for that wire, and (7) type of signal for that wire (such as power or data).
A portion of a sample routing list is shown below.
One final note: There are many other names for a routing list. The name changes from one company to another. Some other names include: (a) wire list, (b) point to point list, (c) pin out list, and (d) termination list.
