adjustment points and may be tightened to fit snugly
on most any load. A complete set of 463L nets (three
nets) weighs 65 pounds.
Other cargo restraints are
chains and chain tic-down devices. These are used
for large items, such as Conex boxes, Seabee shelters,
and refer units, and so forth. Five-thousand-pound
tie-down straps (fig. 2-14) are used to secure
equipment attachments and provide individual item
restraints. Additionally, the tie-down straps provide
supplemental restraint to the 463L pallet nets.
Cargo is palletized from the heaviest to the

smaller items are positioned on top or along the side
of the heavier cargo, Containers marked THIS SIDE
UP are placed upright, and cargo with special labels
are faced outward whenever possible. Pallets should
be constructed in a square or pyramid shape whenever
possible (fig. 2-16). This makes the load stable, easy
to handle, and easier to secure on the pallet. Each
463L pallet requires dunnage under the pallet when
not on board the aircraft. The dunnage consists of
three pieces of 4-inch by 4-inch by 90-inch timber and
is placed in the center and close to the outside edges
of the pallet. This prevents the pallets from warping
and enhances forklift operations. Each aircraft has
restrictions as to the dimensional size and shape
particular to that specific aircraft. Aisleways must be
built on pallet position three or four in a C-130
aircraft. Check the particular requirements of the
aircraft for which the load is prepared.
