weighing and marking station. Weighing and marking procedures are outlined in the Equipment Operator, Advanced,  NAVEDTRA   12537. Palletized  Cargo Cargo that is to be loaded on an aircraft is palletized on 463-L air certified pallets, as shown in figure 6-25. The weight of an empty 463-L pallet is standardized at 290 pounds; when side and top nets are added the pallet weight is 355 pounds. These figures are to be used in weight  and  balance  planning  of  an  aircraft  load  plan. The outside dimensions of a 463-L pallet are 88 inches long and 108 inches wide. The usable space on the pallet is 84 by 104 inches; this leaves a 9-inch space around Figure 6-25.-463-L pallet with cargo and net. 6-34 the outside perimeter of the pallet load. Cargo can be loaded on the pallet up to 96 inches high, and the weight limitation  is  10,000  pounds  per  pallet  maximum. Each pallet has a total of 22 tie-down rings (six on the long side and five on the short side) that match up with the cargo net fasteners. 463-L pallets lock into the aircraft by a rail on each side of the aircraft. When loads are placed on a pallet, three point dunnage must be placed under each pallet. The size of the dunnage must be at least 4- by 4- by 88-inch timbers. One timber must be placed under the center of the pallet and one under each outside edge of the pallet; this helps prevent warping of the pallets. To  store  empty  pallets,  you  should  first  put  down one set of three point dunnage, then stack the pallets no more than 10 high. If more pallets must be stacked, another set of dunnage must be placed on top of the first 10 pallets, then 10 more pallets can be stacked. This sequence can be repeated up to a maximum of 40 pallets. Each pallet must be stacked with the cargo loading surface  facing  in  an  upward  direction. During the pallet-building process (placing cargo on the pallets), always load heavy cargo in the center of the pallet and build it up with lighter cargo around it. This will keep the center of balance at the center of the pallet. All cargo loaded on a 463-L pallet must be placed close together with no open space between them. If space is left between cargo items, the cargo may shift on the pallet during flight and could cause damage to or even loss of the aircraft. ADVANCED BASE PLANNING During  World  War  II  when  bases  were  constructed across the island chains of the Pacific Ocean, it became apparent that significant savings in both time and material  could  be  realized  if  units  of  materials, equipment, and personnel required to perform specific functions  were  standardized.  This  was  the  beginning  of the Advanced Base Functional Components (ABFC) System that is still in use today. This section will briefly cover the ABFC System and the Facilities Planning Guide, NAVFAC  P-437. ADVANCED BASE FUNCTIONAL COMPONENTS  SYSTEM The   Advanced   Base   Functional   Components System is covered in the  Naval  Construction  Force (NCF)  Manual,  NAVFAC P-315, and in volume 2 of the Facilities Planning Guide,  NAVFAC  P-437.  However,
