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.
