Equipment Logistics Control Number (LCN)

The Equipment Logistics Control Number (LCN) is a unique alpha-numeric string assigned to an individual training device or equipment item to specifically and uniquely identify that particular training device or equipment item from all other equipment items having the same Part Number and / or Serial Number.  The Equipment LCN uses a Top-Down-Break-Down construct to define a hierarchical structure of a training device or equipment item and is used to identify all of the components that are associated with, or that comprise, a training device or equipment item.

For the C-17 ATS program the Equipment LCN construct uses a 1, 1, 2, 3, 3, 3, 3 LCN structure – See Equipt LCN Structure.  The LCN structure provides an identification of where a specific item is located within a specific equipment architecture hierarchy, while the LCN construct provides intelligent information regarding not only the equipment architecture but specific information about the equipment elements and equipment items within that architecture; such as what trainer and / or what subsystem within the trainer an item was located when the original trainer / equipment was delivered.

The Equipment LCN performs two major functions.  The first is to aid with identifying all of the equipment items that were a part of the Original equipment As Delivered end item product (i.e. a trainer).   The second function is to aid with identifying where all of the originally acquired equipment items are currently physically located if not still contained in the As Delivered end item product or trainer.

To see all of the major elements associated with a specific LCN enter some portion of that LCN into the Equipt LCN field and then enter the SQL wild card command %.

Clicking on the Lookup icon  at the bottom of the page will bring up a listing of all the items indentured below the LCN specified.  This is the original As Delivered equipment architecture for the trainer showing all of the equipment systems/subsystem and repairable items that were originally delivered with the trainer.  The Location element and the Next Higher Assy. data elements identify where each particular equipment item is currently located.

The above example produces a listing of all the items associated with that particular training site.  Using more of an LCN construct permits a refinement of only those elements associated with a particular part of an LCN structure as shown below for a WST visual system.
